Dascyllus flavicaudus, common name yellowtail dascyllus, is a Damselfish belonging to the family Pomacentridae.
These damselfish can be found in the Eastern Central Pacific, in the southeastern Oceania, including Society Islands, Tuamoto Islands, Pitcairn Islands, and Rapa Nui. It occasionally makes its way into the aquarium trade.
This tropical species is reef-associated and non-migratory. It occurs in coral and rocky reefs at depths of 3 to 40 m.
Dascyllus flavicaudus can grow to a size of 12 cm in length. These fishes have a very height body, with a ratio of 1 / 1.4-1.6 (body height / body length). With the exception of the yellowish to yellowish-white tail and the bright rear portion of the dorsal fin, their body is dark, blackish-brown to blackish-bluish. The dark edges of the scales make a net drawing. They show 12 dorsal spines, 15-16 dorsal soft rays, 2 anal spines and 13-14 anal soft rays. During matings time the males usually turn a shade or two darker, sometimes with white spots. [1]
These fishes have just one of at least two distinct sexes in any one individual organism (Gonochorism). They are oviparous and non-functional hermaphrodite. They mainly feed on copepods, other small planktonic crustaceans and algae. Adults form a permanent harem, with one male and several females close to coral heads. They are substrate spawners and stick their spawn in a cave or hidden niche. Males guard and aerate the eggs that adhere to the substrate.
Pomacentridae is a family of ray-finned fish, comprising the damselfishes and clownfishes. This family were formerly placed in the order Perciformes but are now regarded as being incertae sedis in the subseries Ovalentaria in the clade Percomorpha. They are primarily marine, while a few species inhabit freshwater and brackish environments. They are noted for their hardy constitutions and territoriality. Many are brightly colored, so they are popular in aquaria.
The orange-fin anemonefish is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes, found in the Western Pacific north of the Great Barrier Reef from the surface to 20 m, to include the Pacific Ocean between Queensland, Australia, and New Guinea to the Marshall and Tuamotus Islands. It can grow to 17 cm in length.
Dascyllus is a genus of fish in the family Pomacentridae. They are usually commensals with corals.
Stegastes nigricans, the dusky farmerfish, is a species of damselfish found around coral reefs at a depth of one to 12 meters, in tropical climates between 30°S and 30°N. They are known for farming monocultures of algae such as cyanophores and rhodophytes.
The Indo-Pacific sergeant (Abudefduf vaigiensis) may also be known as the Sergeant major although this name is usually reserved for the closely related species Abudefduf saxatilis.
The threespot dascyllus, also known as the domino damsel or simply domino, is a species of damselfish from the family Pomacentridae. It is native to the Indo-Pacific from the Red Sea and East Africa, to the Pitcairn Islands, southern Japan, and Australia. Its grey to black body has two lateral white spots and one between the eyes like domino hence the name; the threespot dascyllus grows up to 13 cm in length. Coloration is somewhat variable; the spot on the forehead may be absent and the lateral spots very much reduced. It feeds on algae, copepods and other planktonic crustaceans.
Stegastes variabilis is a damselfish in the family Pomacentridae, found on coral and rocky reefs in the Caribbean Sea and neighboring areas of the Atlantic Ocean and Gulf of Mexico. They are often solitary fish.
The ocean surgeon or ocean surgeonfish is a tropical fish known to live in reefs in the Atlantic Ocean. It is edible, and occasionally marketed fresh, but more often they are used as bait or in the aquarium trade.
Acanthochromis polyacanthus, the spiny chromis damselfish, is a species of damselfish from the western Pacific. It is the only member of its genus.
Pomacentrus moluccensis, the lemon damselfish, is a species of bony fish in the family Pomacentridae, from the Western Pacific Ocean. It occasionally makes its way into the aquarium trade. It grows to a size of 9 cm (4 in) in length.
Stegastes planifrons is a damselfish from the Western Atlantic. It occasionally makes its way into the aquarium trade.
Stegastes beebei, is a species of damselfish found on coral and rocky reefs at depths between 0 and 15 m. They are somewhat territorial, and chase away small intruders. They are omnivorous, grazing on algae and nibbling at small crustaceans and the tentacles of anemones. They are oviparous, with distinct pairing during breeding. The eggs are demersal and adhere to the substrate. Males guard and aerate the eggs.
The Barrier Reef chromis, also known as the yellowback puller or shining puller, is a species of damselfish in the family Pomacentridae native to the east coast of Australia. It is a small fish with a yellowish-brown dorsal surface separated by a dark stripe from its silvery flanks and underside.
Neoglyphidodon carlsoni is a species of damselfish in the family Pomacentridae. It is found in the western and central Pacific Ocean. Adults can grow up to a maximum length of 10 centimetres (3.9 in) This fish is omnivourous. Occasionally, they are found in the aquarium trade.
Neoglyphidodon thoracotaeniatus is a species of damselfish in the family Pomacentridae. It is found in the Indo-Pacific mainly in the Pacific Ocean. Adults can grow up to 13.5 centimetres (5.3 in). It is found in the aquarium trade.
Halichoeres leucoxanthus, commonly called the Canarytop wrasse, Whitebelly wrasse, or Lemon meringue wrasse, is a fish species in the wrasse family endemic to the Indian Ocean.
Pomacentrus aurifrons, the yellowhead damselfish, is a species of ray-finned fish from the family Pomacentridae, the damselfishes and clownfishes. It is found in the western Pacific Ocean.
Amphiprion barberi, is a species of anemonefish that is found in the western Pacific Ocean. It was previously considered a geographic color variation of other anemonefish, initially Amphiprion rubrocinctus from 1972 and then Amphiprion melanopus from 1980 however further study and DNA sequencing resulted in A. barberi being described as a new species in 2008. Like all anemonefishes it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host anemone. It is a sequential hermaphrodite with a strict sized based dominance hierarchy: the female is largest, the breeding male is second largest, and the male non-breeders get progressively smaller as the hierarchy descends. They exhibit protandry, meaning the breeding male will change to female if the sole breeding female dies, with the largest non-breeder becomes the breeding male. The fish's natural diet includes zooplankton.
Amblyglyphidodon flavilatus, known as yellow damselfish, yellowfin damselfish, yellow flank damselfish, yellow side damselfish, and yellow-sided Damselfish, is part Pomacentridae, which is a family of ray-finned fish including damselfish and clownfish. This family represents the greatest diversity and abundance of fish species inhabiting coral reefs. They were first discovered in the 1980s by Allen and Randall.
Plectroglyphidodon dickii, common name blackbar devil, Dick's damsel or narrowbar damselfish, is a species of damselfish in the family Pomacentridae. This species was formerly classified as Dascyllus aruanus, but recently the populations of western Indian Ocean and Pacific Ocean have been split off.
