The Fusilier Damselfish, Lepidozygus tapeinosoma, is a strikingly beautiful fish with an elongated cylindrical body and forked caudal fin. Found in the Western Pacific Ocean, this species is often seen swimming alongside other plankton-feeding fishes such as anthias. The base color of its body is a dark greenish hue that gradually turns yellow-green towards the tail, with a pinkish area around the mouth and blue dots. The anal and dorsal fins are lined with blue, and the caudal fin is reddish with a blue tip. Although not commonly kept in aquariums, the Fusilier Damselfish can adapt to prepared foods and is generally peaceful toward other fish species as long as they are not too small.

As an attractive and unique species, the Fusilier Damselfish is a sought-after addition to any aquarium. Its striking coloration and sleek shape make it an eye-catching centerpiece in any tank. While they can be territorial, proper care and ample space can keep aggression to a minimum. It can grow up to 4 inches in length and requires a minimum tank size of 55 gallons. Feed them 2-4 times a day a diet of brine shrimp, mysis shrimp, krill, squid, and other meaty foods.
