Acanthophyllia, often called a "doughnut" or "meat" coral, is a large, solitary stony coral. It's characterized by a single, fleshy polyp that hides a strong, calcium-based skeleton. These corals are known for their vibrant colors, patterns, and intense fluorescence.
Here's a more detailed description:
Appearance: Acanthophyllia are large, single polyp stony corals with a fleshy, meaty appearance, hence the names "meat" or "doughnut" coral. They are not transparent and have a large, solid base.
Skeleton: Underneath the polyp is a thick, hard skeleton made of calcium.
Color and Patterns: They come in a wide range of colors and patterns, including greens, reds, blues, purples, and combinations of these.
Size: Acanthophyllia are known for their large size, making them a prominent centerpiece in reef aquariums.
Growth: They are considered slow-growing stony corals.
Care: They generally require moderate lighting and low water flow. They can also benefit from supplemental feeding of meaty foods like mysis and krill.

Acanthurus triostegus , известен още като затворнически танг , манини , затворническа риба хирург , затворнически хирург или петопорен хирург , е вид морска лъчеперка риба, принадлежаща към семейство Acanthuridae , което включва рибите хирург, рибите еднорожки и танговете. Този вид има широко разпространение в Индо-Тихоокеанския регион .
Таксономия
Acanthurus triostegus е описан официално за първи път през 1758 г. като Chaetodon triostegus от Карл Линей , като описанието е публикувано в 10-то издание на Systema Naturae , катотиповото му находище е посочено като „Индии“. Родът Acanthurus е един от двата рода в трибата Acanthurini , която е една от трите триби в подсемейството. Acanthurinae , което е едно от двете подсемейства в семейство Acanthuridae.
Етимология
Acanthurus triostegus е получилспецифичното име triostegus , което означава „три капака“, това може да се отнася до тритебранхиостегални мембрани .
Описание
Танголият е наречен така заради смелите си черни ивици на жълтеникав фон. Това е странично сгъстена риба с овална форма и максимална дължина около 26–27 см (10–11 инча). Главата е малка, със заострена муцуна и крайна уста с дебели устни. Има шест черни ивици, което го отличава от зебровия танг ( Acanthurus polyzona ), който има девет и има по-ограничен ареал в Индийския океан. Първата черна ивица е коса и преминава през окото. Има две черни петна на опашния ствол, а от всяка страна има остър, прибиращ се шип, който се използва в нападение или защита.
Разпространение и местообитание
Acanthurus triostegus се среща в тропическия Индо-Тихоокеански регион. Ареалът му се простира от източноафриканското крайбрежие и Мадагаскар до югозападна Япония, Австралия и Централна Америка, включително много тихоокеански островни групи. Среща се по твърди дъна в лагуни, рифови склонове, заливи и естуари. Младите екземпляри са често срещани в приливните басейни, а по-големите риби се срещат на дълбочина до около 90 м (300 фута).
Биология
Acanthurus triostegus често се храни в близост до сладководни зауствания, пасейки нишковидни водорасли от скалите. Обикновено тези танги пасат нишковидни водорасли, растящи върху корали или скалисти субстрати. Възрастните се събират на големи пасажи, за да се хранят, и те заливат морските дами, опитващи се да защитят териториите си . Мъжките и женските се събират на групи, за да хвърлят хайвера си .
Използване
Acanthurus triostegus е целева риба за храна в много части от ареала си, а в някои райони е и търговски обект. В Хавай се лови от любители рибари , а също така се лови и за търговия с аквариуми .
Черният Amphiprion ocellaris, известен още като черната буря или клоунът на Дарвин, е поразителна разновидност на обикновения клоун. Тези клоуни са естествено черни като смола с бели ивици, което е в ярък контраст с типичното оранжево и бяло оцветяване. Те са вариант, отгледан в плен, което означава, че не съществуват естествено в дивата природа в черния си вид.
Основни характеристики на черния Amphiprion ocellaris:
Външен вид:
Черно като смола тяло с три ясно изразени бели ивици от всяка страна. Възможно е да имат оранжево петно по лицето си, особено когато са млади, което изчезва с узряването им.
Размер:
Достига максимален размер от около 8 см (3 инча).
Поведение:
Те са известни със симбиотичната си връзка с анемоните, осигурявайки подслон и защита на рибата клоун и почиствайки анемоната. Те също така са териториални по отношение на своя дом - анемоните.
Грижа:
Те имат същите изисквания за грижа като стандартните клоуни от вида Ocellaris. Те се нуждаят от добре установен рифов аквариум с подходяща анемона гостоприемник, като например анемона Bubble Tip.
Диета:
Те са всеядни и лесно приемат замразена, жива, пелетна и люспеста храна.
The Black Da Vinci Clownfish (Amphiprion ocellaris) is a captive-bred, designer variant of the popular False Percula clownfish. Renowned for its artistic, paint-stroke-like white patterns set against a jet-black body, this hardy marine fish combines unique aesthetics with the peaceful temperament and easy care of the standard ocellaris.
Appearance: Features a stark black body (stemming from Darwin and black ocellaris lines) adorned with soft, wavy, and often swirling merged white bands. The tail usually ends in a bold black dot surrounded by white, and the white patterns can spill over onto the dorsal and pectoral fins.
Grading: These fish are selectively bred and graded based on white pattern coverage. Grade A typically has fused white stripes on both sides of the body, while Extreme grades show highly erratic, connected trailing stripes with maximum white coloration.
Size & Growth: Reaches a maximum adult length of about 3 inches (7.5 cm), with females typically growing larger than males.
Lifespan: Can live between 10 and 15 years in a well-maintained home aquarium.
Minimum Tank Size: 20 gallons for a single specimen or a juvenile pair; 30 gallons or more is ideal to allow for natural territorial movement.
Temperament: Peaceful and relatively docile, though they can display mild aggression when establishing territory or pairing up. They are 100% reef safe and will not nip at corals or invertebrates.
Diet: Omnivorous; they readily accept high-quality marine flakes, pellets, and various frozen foods like mysis shrimp, brine shrimp, and ocean plankton.
Host Anemones: While they do not strictly require an anemone to thrive in captivity, they can easily form symbiotic relationships with popular host anemones like the Bubble-Tip Anemone (Entacmaea quadricolor).
The DaVinci Ocellaris Clownfish (Amphiprion ocellaris) is a captive-bred designer morph prized for its unique, swirling white markings that resemble a painter's brushstrokes. Each individual features a completely unique pattern of connected and curvy white bands.
Key Characteristics
Appearance: Features a vibrant orange body with distinctive, flowing white patterns. Unlike standard ocellaris clowns, the white bands are often connected or elongated and delicately edged in black.
Grading: Marketed in different grades based on the amount of white. Grade B features wavy lines with distinct stripes, Grade A has fused stripes on both sides, and Extreme DaVinci features the most white, with multiple stripes connecting.
Origin: This morph does not exist in the wild. It was selectively bred in aquaculture facilities by crossing standard Ocellaris with other designer morphs like the Wyoming White clownfish.
Aquarium Care
Temperament: Peaceful, active, and well-suited for both beginner and advanced marine hobbyists.
Tank Size: A minimum of 75-90 liters (20 gallons) is recommended.
Reef Compatibility: 100% reef-safe. They readily host bubble-tip anemones or even soft corals.
Diet: Omnivorous; easily feeds on high-quality flakes, pellets, and enriched frozen foods like mysis and brine shrimp.
Size & Lifespan: Reaches an adult size of 3 to 4 inches (7.5–10 cm) and can live 8 to 12+ years with proper care.
Amphiprion ocellaris, commonly known as the Ocellaris clownfish or False Percula clownfish, is a small (up to 11 cm/4.3 inches), brightly colored saltwater fish famously depicted in Finding Nemo. It has an orange-to-reddish-brown body with three white, black-outlined bands and a symbiotic relationship with sea anemones.
Physical Characteristics
Coloration: Typically vibrant orange with three vertical white bands: one behind the eye, one in the middle, and one on the tail base.
Color Variations: A naturally occurring black variant exists, often referred to as the Darwin Ocellaris.
Distinctive Features: The middle white band has a forward-projecting bulge. Fins are outlined with fine black lines.
Distinction: A. ocellaris is often mistaken for Amphiprion percula, but ocellaris has thinner black edging around the white bands and a taller dorsal fin.
Eye: Features a muddy brown ring around the pupil, unlike the bright orange ring of A. percula.
Habitat and Behavior
Location: Found in the tropical waters of the Indo-Pacific, including the Great Barrier Reef and Southeast Asia.
Symbiosis: Lives in shallow reefs and lagoons (usually shallower than 50 feet) within the tentacles of specific sea anemones, including Heteractis magnifica and Stichodactyla gigantea.
Social Structure: Known for living in small hierarchical groups, where they are protandrous hermaphrodites—the largest fish is the female, and the next largest is the male.
Diet and Reproduction
Diet: Omnivorous, feeding on plankton, algae, and small invertebrates.
Breeding: They are oviparous (egg-laying) and monogamous. Eggs are laid near the host anemone, and the male is responsible for cleaning and fanning them until they hatch, which usually happens after sunset.
Aquarium Care
Popularity: One of the most popular marine fish for aquariums due to their hardy nature and suitability for captive breeding.
Lifespan: Can live up to 12 years in captivity.
The ocellaris clownfish, or Amphiprion ocellaris, is a vibrant marine fish known for its striking orange body, three white bands, and black outlines. These fish, also called false percula clownfish or common clownfish, form a symbiotic relationship with sea anemones, using their mucus-covered skin to avoid being stung by the anemone's tentacles.
Physical Characteristics:
Color: Primarily bright orange with three distinct white bands.
Bands: The white bands are usually outlined in black. The middle band often has a rounded bulge in the middle.
Size: Typically grow to about 3-5 inches (8-11 cm) in length.
Fins: Black markings on the fins, particularly the dorsal fin, are common.
Other Notable Features:
Symbiotic Relationship:
They have a mutually beneficial relationship with sea anemones, living among their tentacles for protection from predators.
Protective Mucus:
A special layer of mucus on their skin protects them from the anemone's stinging cells.
Protandrous Hermaphrodites:
All begin life as males and can change to females as they mature, with the largest fish in a group typically being female.
Regional Variations:
While typically orange, some can be darker red-orange or even black with white bands, depending on their location.
