Mithraculus sculptus (Emerald Crab) is a popular, hardy, nocturnal reef-safe scavenger (up to 2 inches) known for eating nuisance bubble and hair algae. Native to the Caribbean, they feature a vibrant green, flat shell and hairy legs. They require plenty of live rock for hiding and are generally peaceful, though they may prey on small fish or corals if underfed.
Key Details for the Hobbyist:
Care Level: Easy.
Diet: Omnivore/Herbivore. Consumes bubble algae, green hair algae, and leftover meaty foods.
Tank Conditions: 75–82°F (24–28°C), pH 8.1–8.2, salinity 1.024–1.026.
Behavior: Generally peaceful, but can be opportunistic; may harm small, slow fish or sessile invertebrates if not enough algae is available.
Size: Up to 2 inches (5 cm) in width.
Habitat: Requires plenty of rockwork/crevices.
Reef Safe StatusWhile generally considered reef-safe, Mithraculus sculptus is best described as "reef-safe with caution," as they may pick at soft corals or LPS if they are underfed. They are considered highly effective for managing bubble algae (Valonia) outbreaks.
Mitra papalis, commonly known as the Papal Mitre or Pontifical Mitre, is a species of sea snail in the Mitridae family.

Blotches:
They have several rows of irregular, bright red-orange or purplish blotches.
Aperture:
The aperture is moderately wide and smooth on the inside.
Sutures:
Sutural coronations are present, and the sutures are more adpressed compared to similar species like Mitra stictica.
Similarities to Mitra stictica:
Mitra papalis is similar to Mitra stictica, but it has a longer body form, more adpressed sutures, and wider nodules.
Frozen mysis is a high-protein, flash-frozen fish food that serves as a nutritious staple for both marine and freshwater carnivorous fish, including seahorses and corals. It is rich in protein, vitamins, and essential fatty acids, and is often enriched to enhance the vitality, coloration, and immune system of fish. Because it is flash-frozen shortly after harvest, it retains its natural look and nutritional value without artificial preservatives.
Key features
Nutritional profile: High in protein, with a good balance of fats, vitamins, and minerals. It is a source of omega-3 and other unsaturated fatty acids.
Palatability: Highly palatable, and can entice picky eaters. It is especially popular with seahorses.
Ease of digestion: Easy for fish to digest, which helps with water quality.
Flash-frozen: Preserves nutritional quality and natural appearance.
Processing: Often gamma-irradiated to ensure it is pathogen-free.
Suitability: Suitable for both marine and freshwater species, including fish, corals, and invertebrates.
Feeding instructions
Feed only as much as your fish can consume within a 2-5 minute period.
It is best to feed small amounts multiple times a day to mimic natural grazing behavior.
Avoid thawing the cubes before feeding; the food will defrost in the water.
Remove any uneaten food promptly to help maintain water quality
Nardoa galatheae, commonly known as the brown mesh sea star or green sea star, is a species of sea star belonging to the Ophidiasteridae family. It is found in the Indo-Pacific region, typically inhabiting coral reefs and rocky substrates at depths less than 30 meters. These sea stars are omnivores, feeding on detritus, small invertebrates, and algae.
Key Features of Nardoa galatheae:
Appearance: They have a characteristic five-armed formation with a mottled, greenish-brown color.
Habitat: N. galatheae prefers shallow rocky reefs, sandy substrates, and areas with live rock containing algae.
Diet: They feed on detritus, small microbes, algae, and may also consume small invertebrates.
Aquarium Care: These sea stars are not tolerant of sudden changes in water chemistry and should be drip-acclimated. They also cannot tolerate copper-based medications.
Size: They typically grow to an average of 25 cm in diameter.
Distribution: They are found in the Indo-Pacific region.
Nardoa novaecaledoniae, also known as the Goldtip Starfish, Yellow Mesh Sea Star, or Peach Tip Mesh Sea Star, is a species of sea star in the family Ophidiasteridae. These starfish are found in the Indo-Pacific region, including areas like Australia, Indonesia, and the Philippines.
Key features of Nardoa novaecaledoniae:

Habitat: They typically inhabit shallow, rocky reefs.
Diet: They are omnivores, feeding on algae, small fish, and mussel flesh.
Care: They are not commonly seen in the home aquarium trade and can be sensitive to sudden changes in salinity.
Range: They are found in the Western Pacific Ocean.
Nassarius snails are small, carnivorous marine snails with a distinctive, oval-shaped, spiral shell. They are known for their efficient scavenging of detritus, uneaten food, and other organic waste, and are helpful in cleaning up and aerating aquarium substrates.
Key features of Nassarius snails:
Appearance:
They have a small, oval shell, often tan or brownish in color. They also possess a long, tube-like siphon that protrudes from the sand when feeding.
Behavior:
Nassarius snails are burrowers, spending most of their time under the sand and emerging when food is detected. Their burrowing helps to aerate the sand bed, which is beneficial for maintaining a healthy aquarium.
Diet:
They are scavengers that feed on detritus, decaying organic matter, uneaten food, and fish waste. They do not consume algae.
Benefits:
Nassarius snails are valuable additions to a clean-up crew in aquariums. They help to remove waste, aerate the substrate, and maintain a healthy environment.
Care:
They are relatively easy to care for and thrive in well-established reef tanks with a deep sand bed. They require a stable environment and a varied diet, including sinking pellets and occasional meaty foods.
Naso brevirostris, also known as the short-nosed unicornfish, spotted unicornfish, brown unicornfish, lined unicornfish, longnose surgeonfish, palefin unicornfish, paletail unicornfish, shorthorned unicornfish or shortsnouted unicornfish, is a species of marine ray-finned fish belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs. It occurs in the Indian Ocean and western Pacific Ocean.
Taxonomy
Naso brevirostris was first formally described as Naseus brevirostris in 1829 by the French zoologist Georges Cuvier with its type locality not given but considered to be Indonesia.[3] It 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 brevirostris has a specific name which means "short nose".
Description
Naso brevirostris has 6 spines and between 27 and 29 soft rays supporting the dorsal fin while the anal fin is supported by 2 spines and 27 to 29 soft rays. The depth of the body fits into its standard length between roughly 2 and 2.7 times. The snout is very short in length and is very steep, almost vertical. Subadults and adults have long, tapering bony protuberances in front of their eyes which may extend past one's mouth by as much as the length of the head, first appearing as a bump in individuals of around 10 cm (3.9 in) total length. A pair of bony plates with a poorly developed keels are on each side of the caudal peduncle and the caudal fin varies from truncate to slightly rounded.
The overall colour is light blueish-grey to olive-brown, although there is a colour phase where the front quarter of the body is pale with a clear demarcation from the remainder of the body. The middle of the flanks are marked with thin, vertical dark grey lines that break up into small spots on the lower body. The head is marked with small dark spots or by a lattice of lines. The protuberance is marked with diagonal black lines, the membrane of the operculum is white, the lips have pale blue edges and the caudal fin is largely whitish.This species has a maximum published total length of 60 cm (24 in).
Distribution and habitat
Naso brevirostris is widespread throughout the Indian and Pacific Oceans, from the Red Sea south along the eastern coast of Africa as far as Durban in South Africa and eastward across the Indian Ocean into the Western Pacific Ocean, extending east to the Pitcairn Islands and the Hawaiian Islands, north to southern Japan and south to Australia.[1] In Australia the distribution goes from Ningaloo Reef around the northern tropical coasts to the northern Great Barrier Reef and the Coral Sea as far south as Moreton Bay in Queensland, as well as in the region of Lord Howe Island in the Tasman Sea.In the eastern Pacific it is found around the Galápagos Islands.These fish live in lagoon and seaward reefs down to depths of 46 m (151 ft)
Naso brevirostris forms spawning aggregations, pairing to spawn and the males have larger keels on the caudal peduncle than the females. The eggs hatch into pelagic larvae which may remain in the water column for up to 90 days and the adults attain sexual maturity at around 25 cm (9.8 in).Adults feed mainly on gelatinous zooplankton, while juveniles mainly feed on benthic algae. The switch from grazing to preying on gelatinous zooplankton coincides with the development of the bony protuberance.
Naso elegans, the elegant unicornfish, the blonde naso tang, Indian orange-spine unicorn, lipstick surgeonfish, lipstick tang, orangespine unicornfish or smoothheaded 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 Indian and western Pacific Oceans.
Taxonomy
Naso elegans was first formally described as Aspisurus elegans in 1829 by the German zoologist and explorer Eduard Rüppell with its type locality given as the northern Red Sea. This species is classified within the nominate subgenus of the genus Naso.[The genus Naso is the only genus in the subfamily Nasinae in the family Acanthuridae. For a long time this species was regarded as an Indian Ocean colour morph of the orangespine unicornfish (Naso lituratus) until it was shown that there were consistent meristic differences.
Etymology
The specific epithet elegans is Latin for "choice", "fine" or "select", a reference to the beautiful colours of this fish.
Distribution and habitat
Naso elegans is found in the Indian and Pacific Oceans. It occurs in the Red Sea south along the east African coast to Durban in South Africa and eastward across the Indian Ocean into the Pacific where it reaches as far east as Bali in Indonesia. It is absent from the waters off the mainland Indian subcontinent.[1] In Australian waters it has been recorded from Christmas Island and the Cocos (Keeling) Islands. The elegant unicornfish occurs in reef flats in coastal and inshore waters in small schools while in more oceanic waters it forms larger schools,
Description
Naso elegans has 6 spines and between 26 and 30 soft rays, typically 28, supporting the dorsal fin while the anal fin is supported by 2 spines and between 27 and 30 soft rays, typically 29. The pectoral fin contains 16, or more usually, 17 fin rays. There are between 30 and 35 teeth in each jaw and, in adults, these are similar to incisors and have rounded edges. The body has a depth which is equivalent to roughly a quarter of the standard length and it grows more elongate as the fish grows.The keels on the caudal peduncle are larger in males than in females and the males also have longer filaments growing from the caudal fin. The overall colour is grey, with a dark snout separated from the grey head by a yellow bar at the eyes. The dorsal fin is yellow with a thin blue edge and a black band inside that. The anal and pelvic fins are dark brown.The plates on the caudal peduncle are vivid orange separated by a patch of white.The caudal fin is yellowish with a black submarginal band and black lower and upper edges. The elegant unicornfish has a maximum total length of 45 cm (18 in), although 35 cm (14 in) is more typical.
Biology
Naso elegans is a herbivore, feeding on benthic algae,[8] particularly brown algae in the genera Sargassum and Dictyota.
The elegant unicornfish, Naso elegans, is a marine fish known for its distinctive coloration and markings. It has a dark snout, a yellow bar above the eyes, and a yellow dorsal fin with a narrow blue margin and a black submarginal band.

Naso lituratus, the clown unicornfish, orangespined unicornfish, black-finned unicornfish, Pacific orangespined unicornfish, blackfinned unicornfish or stripefaced unicornfish, is a species of marine ray-finned fish belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs. This fish is found in the eastern Indian Ocean and western Pacific Ocean.
Unique to members of Acanthuridae, including Naso lituratus, are the Epulopiscium bacteria. These bacteria influence the digestion of Naso lituratus, helping them process the algae in their diet.[3][4][5]
Naso lituratus can be found in the Indian Ocean and the Pacific Ocean. This species can be easily recognised by two bright orange forward-hooked spines on the caudal peduncle (the tail base), its orange lips and black face mask. The body is brownish grey with yellow nape and there is a broad black band on the dorsal fin. It reaches about 45 cm (18 in) in length.
It can be found on coral reefs, often in pairs.
Taxonomy
Naso lituratus was first formally described in 1801 as Acanthurus lituratus by the German naturalist Johann Reinhold Forster without stating a type locality, although this is considered to be Tahiti in the Society Islands of French Polynesia.[7] This species is classified within the nominate subgenus of the genus Naso.[8] The genus Naso is the only genus in the subfamily Nasinae in the family Acanthuridae.
Description and biology
The features of Naso lituratus include orange lips, a caudal peduncle with a brash-hooked spine, and a black face mask. The descriptions of these features include one dorsal fin on top of head and is encircled by a broad black band around 45 centimeters long. They barely grow in size. Long anal fin with II spines and 28–30 soft rays, and a continuous, unnotched dorsal fin with VI spines and 27–30 soft rays. Contains 8 to 9 gill rakers on the lower leg whereas the upper limb has 4. There are 6 spines in total, each with 26–29 soft rays. Adipose fins do not exist. There is one anal fin, two spines overall, and between 27 and 30 soft rays on it. The pectoral and pelvic fins are two of its paired fins. The pectoral fin contains 17–18 soft rays and 0 spines. The pelvic fin has a single spine and three soft rays. In adult males, the lobe's apex produces a lengthy filament. Caudal fin is lunate or crescent-shaped. Two sharp blades that point forward are on the caudal peduncle. In Juveniles, their blades are not fully grown, as they have a stifling gray-brown tint with black, yellow, and white patterns. No forehead "horns" or front protuberance that can be seen in certain other Acanthuridae species.
Distribution and habitat
Naso lituratus live in the East Indian and Pacific Ocean, with their habitat is living in the coral reefs that lay around in those specified oceans. The reproduction of this species are that the sexes are separate among the Acanthuridae and have distinct differences in size. Spawning occurs year round in Guam. They need high oxygen levels, strong water currents, same companions and need to feed on wild algae. Their self defense tactic is that they will extend their strong tail spines to strike any approaching predators.
Naso lituratus has various human use including as a food source and as a commodity in the pet and aquarium trade.
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.
Nemateleotris magnifica (Firefish Goby) , often found hovering near a burrow entrance, with the male guarding the eggs until they hatch. The male and female are similar in appearance, but the male's elongated first dorsal spine may be slightly more prominent.
Specific Characteristics:
Appearance:
The Firefish Goby is known for its distinct coloration: a pearly white front half, transitioning to an orange-red rear half, and a dark red tail. The first dorsal spine is greatly elongated and white.
Behavior:
They are generally peaceful fish and spend most of their time suspended near a refuge, often a burrow, waiting for small prey to drift by.
Pair Behavior:
In the wild, they often live in pairs or small groups, hovering over the reef and actively hunting for food.
Diet:
They are carnivores, feeding on zooplankton, small invertebrates, and in aquariums, they readily accept brine shrimp, mysis shrimp, and prepared marine foods
