Acanthurus triostegus, commonly known as convict tang, manini,convict surgeonfish, convict surgeon, or fiveband surgeonfish, is a species of marine ray-finned fish belonging to the family Acanthuridae which includes the surgeonfishes, unicornfishes and tangs. This species has a wide Indo-Pacific distribution.
Taxonomy
Acanthurus triostegus was first formally described in 1758 as Chaetodon triostegus by Carl Linnaeus, the description being published in the 10 edition of Systema Naturae with its type locality given as "Indies".The genus Acanthurus is one of two genera in the tribe Acanthurini which is one of three tribes in the subfamily Acanthurinae which is one of two subfamilies in the family Acanthuridae.
Etymology
Acanthurus triostegus was given the specific name triostegus which means "three covers", this may refer to the three branchiostegal membranes.
Description
The convict tang is so called because of its bold black stripes on a yellowish background. It is a laterally-compressed oval-shaped fishwith a maximum length of about 26–27 cm (10–11 in). The head is small with a pointed snout and a terminal mouth with thick lips. It has six black stripes which distinguishes it from the zebra tang (Acanthurus polyzona) which has nine, and has a more restricted range in the Indian Ocean. The first black stripe is oblique and passes through the eye. There are two black spots on the caudal peduncle, and on each side there is a sharp, retractable spine, which is used in offence or defence.
Distribution and habitat
Acanthurus triostegus occurs in the tropical Indo-Pacific region. Its range extends from the East African coast and Madagascar to southwestern Japan, Australia and Central America, including many Pacific island groups. It is found over hard bottoms in lagoons, reef slopes, bays and estuaries. Juveniles are common in tide pools, and larger fish are found at depths down to about 90 m (300 ft).
Biology
Acanthurus triostegus frequently feed in the vicinity of freshwater discharges, grazing filamentous algae off the rocks.Typically these tangs graze on filamentous algae growing on coral or rocky substrates. The adults aggregate in large schools to feed and these overwhelm damselfishes attempting to defend their territories. The males and females gather in aggegations to spawn.
Utilisation
Acanthurus triostegus is targeted as a food fish in many parts of its range and in some areas is commercially targeted. In Hawaii it is fished for by recreational anglers and it is also caught for the aquarium trade.
Ctenochaetus tominiensis, the Tomini surgeonfish, Tomini bristletooth, yellowtip bristletooth or orangetip bristletooth, is a species of marine ray-finned fish belonging to the family Acanthuridae which includes the surgeonfishes, unicornfishes and tangs. This fish is found in the western central Pacific Ocean.
Taxonomy
Ctenochaetus tominiensis was first formally described in 1955 by the American ichthyologist John Ernest Randall with its type locality given as Sadaa Island in the Gulf of Tomini, Sulawesi, Indonesia.The genera Ctenochaetus and Acanthurus make up the tribe Acanthurini which is one of three tribes in the subfamily Acanthurinae which is one of two subfamilies in the family Acanthuridae.
Description
Ctenochaetus tominiensis has its dorsal fin supported by 8 spines and 24 or 25 soft rays while the anal fin is supported by 3 spines and 22 or 23 soft rays. The rear ends of the dorsal and anal fins are, uniquely in the genus Ctenochaetus, angular. The lips have warty margins. In juveniles the caudal fin is forked and in adults it is lunate. The maximum published standard length of this fish is 16 cm (6.3 in).The overall colour of the body is yellowish brown with a white caudal fin and broad yellow margins to the dorsal and anal fins.
Distribution and habitat
Ctenochaetus tominiensis is found in the western central Pacific Ocean from Malaysia and Indonesia east through East Timor, the Philippines, Palau, Micronesia, Papua New Guinea, the Solomon Islands, Tuvalu, Vanuatu and Fiji, south to the Great Barrier Reef. It has been recorded from Tonga.This species is found solitarily or in small aggregations on steep drop offs with dense coral growth in inshorse, sheltered waters at depths between 0 and 45 m (0 and 148 ft).
Echinaster sepositus, the Mediterranean red sea star, is a species of starfish from the East Atlantic, including the Mediterranean Sea.
Description
Echinaster sepositus has five relatively slender arms around a small central disc. It usually has a diameter of up to 20 cm (8 in), but can exceptionally reach up to 30 cm (12 in).It is a bright orange-red in colour, and has a soapy surface texture unlike superficially similar Henricia starfish (another somewhat similar species from the same region is Ophidiaster ophidianus). The surface is dotted with evenly spaced pits from which the animal can extend its deep red gills (papula).
Distribution
Echinaster sepositus is found in the East Atlantic north of the Equator, including the Mediterranean Sea where it is one of the most common starfish (although virtually absent from some localities). Its northern limit is the English Channel, but only on the French side. It is found at depths of 1 to 250 m (3–820 ft) in a wide range of habitats, including rocky, sandy and muddy bottoms, and sea grass meadows (Posidonia oceanica and Zostera)
Synchiropus sycorax, also known as the Ruby red dragonet, is a small, brightly colored fish with a distinct appearance. It features a bright red body and head, yellow belly and pelvic fins, and is adorned with white spots. The first dorsal fin of mature males is large and sail-like. These fish are known for their vibrant colors, unique behavior, and reef-safe nature.
Detailed Description:
Coloration: The head and body are bright red with prominent white spots. The belly and pelvic fins are yellow, and the pelvic-pectoral membrane of males may have a bluish or greenish-grey to black band.
Body Shape: It has a large head, top-mounted eyes, and a small, pointed mouth.
Fin Structure: The first dorsal fin of mature males is large and sail-like. The dorsal fin has well-defined stripes and short filaments.
Spot Pattern: The body has three rows of white spots: one along the lateral line, another above the anal fin, and a middle row extending from above the pectoral fin.
Size: Synchiropus sycorax is a relatively small fish.
Additional Information:
Synchiropus sycorax is a popular aquarium fish due to its vibrant colors, interesting behavior, and reef-safe nature.
They are known to be slow-moving, deliberate feeders and should not have to compete for food.
Their diet includes bloodworms, glassworms, and small invertebrates.
The royal gramma (Gramma loreto), also known as the fairy basslet, is a species of fish in the family Grammatidae native to reef environments of the tropical western Atlantic Ocean. They are commonly kept in aquariums.
Appearance
The fish can be a light purple to a deep violet starting at the head which fades mid-body to a golden yellow at the tail. The royal gramma will also have a small black spot on the front of the dorsal fin and a black line that streaks through the eye. It resembles the false gramma (Pictichromis paccagnellae), with the two main differences between the two being the false gramma has clear fins and does not fade, but rather has a distinct change in color. The royal gramma is relatively small, averaging slightly over 8 cm (3.1 in) and has been tank bred. The largest scientifically-measured royal gramma was 8 cm (3.1 in) long.
Diet
The royal gramma is a planktivore, eating mostly zooplankton and crustaceans. The royal gramma is also a cleaner fish. It removes the ectoparasites (a parasite that lives on the skin of a fish) from other fish and learns to eat dead food, such as crustaceans and fish flesh. They prefer to pick their food from the middle of the water coTheir natural range covers the Bahamas, Venezuela, Antilles, Bermuda, and through the waters surrounding Central America and the northern part of South America. The Royal Gramma tends to swim more towards the bottom with the depth range between 1 and 20 m (3 and 60 ft).
In the aquarium
Due to their relatively peaceful nature, diet, and small size, the royal gramma is considered an ideal inhabitant for most reef aquaria containing coral and other invertebrates. Notwithstanding this general statement, they can become aggressive towards tank-mates when kept in smaller nano reef tanks. They stake out territories throughout rocks and crevices and choose favorite hiding places. They are generally peaceful fish, but are very protective of their territories and are known for chasing out other small fish. They tend to stay in one area of the tank and, when startled, will dart back into their holes. They will vigorously guard their hiding places and, when threatened, will open their mouths wide in a threatening gesture to ward off the intruders. The royal gramma tends to orient itself to be parallel with the surface to which it is closest, resulting in the fish swimming straight up and down or sometimes upside down beneath ledges. This behavior is not to be mistaken for illness.
The minimum suggested tank size is 30 gallons and the tank should not receive sharp lighting. The ideal water temperature should range between 72 and 78 °F and the water pH should be between 8.1 and 8.4, with specific gravity of 1.020–1.025. They are often kept in reef aquaria and are generally kept singly or in pairs. However, small groups can be kept as long as the tank is large enough and has enough cracks and crevices for each fish to have its own territory. The royal gramma should not be kept with its own kind unless in a formed male-female pair. It should also not be kept with larger, aggressive fish that will eat them. They are, however, resistant to most diseases and make very good beginner fish. It will also accept frozen and meaty foods, such as brine shrimp and mysis shrimp in the wild. The royal gramma is very easy to feed, but rotating their foods is said to keep them from becoming picky. Captive royal gramma will also eat flake and pellet foods.
Breeding
Although pairs are difficult to find because the difference between male and female is not visible, they are very easy to breed. With males usually being larger than females, the male will build the nest among rocks using pieces of algae.The male will then lead the female to the nest, where she will deposit 20–100 eggs in the nest. The male exhibits the following nest care practices: protecting the nest and eggs, ongoing maintenance, frequent debris removal, and constant barging into the nest.During the breeding period, this behavior is repeated almost every day for a month or longer. The eggs are about 1 mm (0.04 in) and are equipped with small protuberances over the surface with tiny threads extending from them. These threads hold onto the algae of the nest and keep the eggs in place. The eggs will hatch in five to seven days, normally in the evening, and can feed on rotifers until they are large enough to consume newly hatched brine shrimp
The flame angelfish (Centropyge loricula) is a marine angelfish of the family Pomacanthidae found in tropical waters of the Pacific Ocean.[3] Other common names include flame angel, flaming angelfish and Japanese pygmy angelfish.
Description
The flame angelfish's coloration is bright orange-red with a vertical elongated black spot and four or five bars on the sides, the posterior part of the dorsal, and anal fins, with alternating short purple-blue and black bands. Specimens from the Marquesas lack the vertical black bars.Males are generally larger and slightly more colored than females.
The life span of the flame angelfish is 5–7 years or more.
Range
It if found in various reefs of Oceania, most common in Marshall, Line and Cook Islands. The fish is also, although less commonly, found in the Hawaiian Islands. Particularly, the flame angelfish can be found on the foreslope of coral reefs and clear lagoons.
Diet
In the wild, the flame angelfish has a varied diet consisting of algae and crustaceans. There are occasional specimens that live very long lives in reef aquaria, but the majority of these fish will often die for no apparent reason when they are older. This may be easily explained as many of the Centropyge family are predominantly plankton eaters as juveniles and will switch to consuming its natural adult diet once fully grown. Sometimes, all it takes is for an underfed individual to "test" a food source. This being the case, angelfish are usually added to a well established tank and fed frozen mysis shrimp or meaty crustaceans such as shrimp and clam.
In aquarium
In captivity, this species feeds on a variety of food including brine shrimp, mysis shrimp, and other meat as well as spirulina, seaweed sheets, and pellets, also from personal experience[opinion] they favor tuna and table shrimp.
The flame angelfish is known to be shy upon introduction to an established aquarium, especially smaller specimens; but, within a week, it will gain confidence and is then constantly seen grazing around live rock during the day.
The flame angelfish is often considered reef safe. They will adapt to a captive diet quickly which will usually prevent them from consuming soft or stony corals. Individual specimens that do pick at coral or clam mantles are more often than not under fed or under nourished.
Breeding
The flame angelfish has been known to spawn in captivity, with successfully captive bred specimens offered by Atoll Farm Aquaculture in Thailand. The flame angelfish is haremic in the wild and can be kept in pairs or trios in an extra-large aquarium. The aquarium should contain only one male—the males have more blue on the outer edge of the dorsal and anal fins, and tend to be larger. The fish will spawn toward the end of the day and release pelagic gametes into the water column. Collecting the eggs and raising the larvae is the biggest challenge. The flame angelfish are broadcast spawners, releasing eggs and sperm simultaneously at dusk. They rise into the water column and release their eggs and sperm at the top.
The copperband butterflyfish (Chelmon rostratus), also known as the beaked coral fish, is found in reefs in both the Pacific and Indian Oceans. This butterflyfish is one of the three species that make up the genus Chelmon and all have long beaks.
Description
These fish are easily identified by the yellow banding and long snout. The young fish are similar in appearance to adult fish. Butterflyfish grow up to 20 cm in length.The fish appears taller than its length because of its compressed, deep-bodied form with a long dorsal and posterior fins as well as its vertical yellow stripes on a white background. The snout is long and slender, and the dark eye of the fish is less conspicuous than the dark eye-spot on the dorsal fin. The base of the tail features a dark band that runs perpendicular to the tail. Butterflyfish may be distinguished from the similar C. marginalis by their color pattern and number of dorsal fin rays.
Habitat
Copperband butterflyfish are found at depths of 1−25 metres either alone or in pairs. These fish form monogamous pairs during breeding. They are usually found on coral reefs or rocky shorelines, and also in estuaries and silty inner reefs. This species is territorial and oviparous.
In the aquarium
Copperband butterflyfish can grow to 8 inches (20 cm) but in a home aquarium are usually half that size.[citation needed] They do well at a normal reef temperature range of 75 to 84 °F (24 to 29 °C), with a tank size of at least 75 gallons and plenty of live rock to graze on. This species can be considered reef safe. It will eat many invertebrates, including parasitic forms such as tubeworms, Calliactis parasitica and common glass anemone (Aiptasia, parasitic anemone). Many aquarists introduce the Copperband Butterfly just to get rid of these pests without giving consideration to their long term needs for survival. Given a choice, Aiptasia is the least favored food. The butterflyfish preys on all tube and substrate worms, clams, and mollusks. This is not a recommended fish for inexperienced aquarists, as it requires excellent tank conditions to thrive or even survive.
Naso vlamingii, the bignose unicornfish, scibbled unicornfish, Vlaming's unicornfish, and zebra unicornfish, is a species of marine ray-finned fish belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs. This species is found in the Indo-Pacific.
Taxonomy
Naso vlamingii was first formally described as Naseus vlamingii in 1835 by the French zoologist Achille Valenciennes with its type locality given as Molucca Island in Indonesia.[3] This species is classified within the nominate subgenus of the genus Naso.[4] The genus Naso is the only genus in the subfamily Nasinae in the family Acanthuridae.
Etymology
Naso vlamingii has the specific name which honours the Dutch explorer Admiral Cornelis de Vlamingh who collected specimens and drew illustrations of fishes for the Muséum national d’Histoire naturelle and Valenciennes based his description on one of Vlamingh's illustrations.[4]
Description
Naso vlamingii has 6 spines and 26 or 27 soft rays all of similar height supporting the tall dorsal fin and 2 spines and between 27 and 29 soft rays supporting the anal fin. It has a relatively deep body with standard lengths ranging from 2.2, in subadults, to 2.6, in adults, times the body's depth. There is an obvious bulbous protuberance growing from the head above the snout. There are two bony plates on each side of the caudal peduncle and these have keels with anterior pointing spines. The adults develop long filaments from the tips of the caudal fin lobes. The overall colour of the adults is greyish-brown or reddish brown, and they have the ability to change colour quickly, with small dark blue spots on the head and upper flanks. These spots join up to form stripes on the lower flanks. There is a wide blue band running from the eye to the front of the bulbous protuberance. The lips are blue and there is an irregular blue blotch to the rear of the base of the pectoral fin. The caudal fin is blue at its base, grey in the middle with an ill-defined yellow marginand blue outer edges of the lobes and this extends onto the filaments. The intensity of the colour of the blue markings can be increased to a brilliant blue when the fish is displaying in courtship or to communicate with cleaner fish at cleaning stations.This species has a maximum published length of 60 cm (24 in).
Distribution and habitat
Naso vlamingii has a wide Indo-Pacific range which extends from the eastern coast of Africa between Kenya and South Africa, through the Indian Ocean islands, but it is absent the continental southern Asian waters, through the Andaman Sea, Indonesia and into the Pacific. In the Pacific it extends north to southern Japan, east to the Galápagos Islands and south to New Caledonia and Australia.[1] In Australia the species is found at a number of offshore islands and reefs, as well as from the northern Great Barrier Reef south to waters off Sydney in New South Wales and in the waters around Lord Howe Island in the Tasman Sea. The bignose unicornfish is found in deep lagoons and seaward reefs, frequently aggregating in schools that feed on zooplankton around the higher areas of deep slopes and drop-offs.
Biology
Naso vlamingii can live up to 40 years in captivity.[8] Their eggs are fertilized externally after being released in batches by the female. Spawning typically occurs in aggregations, where many individuals come together to release their eggs and sperm simultaneously. They change their feeding pattern throughout their lives. Juveniles are herbivores; feeding mainly with algae, semi-adults are omnivores and adults are primarily carnivores; hunting for zooplankton.
Centropyge bispinosa, commonly known as the Coral Beauty Angelfish or Dusky Angelfish, is a small, colorful angelfish with a distinctive appearance. They have a bright orange body with vertical blue or purple "tiger" stripes, and a blue-purple head, dorsal, caudal, and anal fins. Their pectoral and pelvic fins are typically yellow or orange.
Key Characteristics:
Color: Orange body with blue/purple stripes, blue/purple head and fins.
Size: Reaches up to 4-5 inches (10-12 cm) in length.
Behavior: Peaceful, but can be territorial with their own kind and other dwarf angelfishes.
Habitat: Found on outer reef slopes and in rocky areas with hiding spots.
Diet: Primarily eats algae and detritus.
Reproduction: Protogynous hermaphrodites, meaning they can change sex.
Reef Compatibility: Considered reef-safe, but individuals may nip at certain corals, especially soft corals.
Distribution:
Found in the Indo-Pacific region, including Australia, Japan, the Philippines, and other tropical waters
Most commonly found is pure blue, dark blue, or light blue, although observers find the aqua, purple, or orange variation throughout the ocean. These sea stars may grow up to 30 cm (11.8 in) in diameter, with rounded tips at each of the arms; some individuals may bear lighter or darker spots along each of their arms. Individual specimens are typically firm in texture, possessing the slightly tubular, elongated arms common to most of other members of the family Ophidiasteridae, and usually possessing short, yellowish tube feet. An inhabitant of coral reefs and sea grass beds, this species is relatively common and is typically found in sparse density throughout its range. Blue stars live subtidally, or sometimes intertidally, on fine (sand) or hard substrata and move relatively slowly (mean locomotion rate of 8.1 cm/min).
The genus Linckia, as is true of other species of starfish, is recognized by scientists as being possessed of remarkable regenerative capabilities, and endowed with powers of defensive autotomy against predators.Although not yet documented, L. laevigata may be able to reproduce asexually. L. laevigata is apparently not an exception to this behavior, as many individuals observed in nature are missing arms or, on occasion, in the comet form.
This sea star is fairly popular with marine aquarium hobbyists, where it requires a proper, slow acclimatization before entering the tank system, and an adequate food source similar to that found in its natural habitat. Generally thought of as a detritivore, many sources maintain that this species will indefinitely graze throughout the aquarium for organic films or sedentary, low-growing organisms such as sponges and algae. In the marine aquarium hobby, they have been seen to consume Asterina Starfish, which are commonly introduced into such aquaria on the ubiquitous "live rock" used in such settings.
Sabellastarte spectabilis, commonly known as the Indian feather duster worm or feather duster worm, is a tubicolous marine polychaete worm. These worms are characterized by their beautiful, feathery tentacles, which they use to filter feed and breathe. They live in leathery tubes, often covered with mud, and are found in tropical and subtropical waters.
Appearance:
Color: Vibrant colors can range from reds, oranges, to purples.
Tentacles (radioles): The tentacles are feathery and arranged in a fan-like structure, creating a striking display when the worm is active. They are striped in dark and pale brown bands.
Tube: The worms secrete a leathery tube that protects them.
Size: Can reach up to 80 millimeters in length and 10-12 millimeters in width.
Habitat and Behavior:
Location: Native to tropical waters of the Indo-Pacific but have spread to other regions.
Tube: The tubes are typically buried in the sediment.
Filter Feeding: They use their tentacles to capture small particles of organic matter from the water.
Sedentary Lifestyle: They primarily live within their tubes and do not move much.
Reproduction and Other Characteristics:
Asexual Reproduction: They can reproduce asexually by fragmentation.
Regeneration: They can regenerate body parts if damaged.
Aquarium Popularity: They are popular in aquariums due to their beauty and helpfulness in removing organic particles from the water.
The Turbo fluctuosa, commonly called the Mexican Turbo Snail or Super Turbo Snail, is a marine gastropod mollusk known for its unique, top-shaped shell and its effectiveness at consuming algae. These snails are popular in reef aquariums due to their ability to quickly remove nuisance algae, including hair algae, from live rock and aquarium glass.
Key characteristics:
Shell: The Turbo fluctuosa has a thick, top-shaped shell with an iridescent interior. The shell can be olivaceous, green, brown, or grayish, with white longitudinal stripes or spots.
Diet: It's a herbivore that feeds primarily on algae, including hair algae, cyanobacteria, and diatoms. It is also known to consume Asparagopsis algae, which can be problematic in reef aquariums.
Behavior: These snails are active both day and night and move slowly over surfaces, grazing on algae. They can bulldoze loose rocks in search of food, so aquariums with well-secured rockwork are recommended.
Aquarium Care: Turbo fluctuosa snails thrive in well-established tanks with plenty of live rock and are compatible with most reef aquarium inhabitants. Adequate calcium levels are needed for shell growth, and supplemental feedings with dried seaweed may be necessary if algae levels are low.
Origin: They are native to the Gulf of California, off the coast of Mexico.
Size: They can grow up to 2 inches in diameter
