Dascyllus flavicaudus, common name yellowtail dascyllus, is a Damselfish belonging to the family Pomacentridae.

Contents

Distribution

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.

Habitat

This tropical species is reef-associated and non-migratory. It occurs in coral and rocky reefs at depths of 3 to 40 m.

Description

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]

Biology

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 family of fishes

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.

<i>Amphiprion barberi</i> species of fish

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.

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.
