Native to the Indo-Pacific Ocean area, it is also known as a Blacktail Humbug and a Blacktail Dascyllus. The body is silver and has four black bands. One band covers the eye, another begins at the first dorsal spine, the third at mid-dorsal and the last at the end of the tail. Typically found living around coral heads, it is a docile fish as a juvenile then becomes aggressive in adulthood, much like most damselfish. Very territorial, it will defend against fish many times its own size.
Size: 1/2" to 1"; can get up to 3"
No. in Tank: singularly or one mated pair
Tank: min. 30 gallons
Food: (Omnivore) Needs a varied diet including mysid shrimp, brine shrimp, marine algae and herbivore preparations
Adaptation: If adding a mated pair, they must be introduced at the same time. It needs caves to hide in and plenty of room in which to swim. Acclimation process will take two or more hours to fully complete.
Compatibility: Ideal for reef systems as they do not threaten corals, clams or invertebrates. Tank-mates should only be aggressive fish; small docile fish will be picked on. Can be kept with other aggressive damselfish, except its own kind.
