Japanese Swallow Angelfish; Female - Genicanthus melanospilos

Japanese Swallow Angelfish Overview

The Japanese Swallow Angelfish, also known as the Blackspot Angelfish or Blackspot Lyretail Angelfish, displays striking sexual dimorphism. Females are yellow dorsally and light blue ventrally, with marine-blue caudal fins highlighted by a dark blue-black edge. Males, on the other hand, have pale bodies with vertical red stripes and a forked tail that is bright blue and yellow. This angelfish thrives in a large tank (at least 125 gallons) with plenty of hiding spots and live rock for grazing. Unlike most angelfish, the Japanese Swallow Angelfish is an excellent reef dweller and will not nip at soft or stony corals. It is also more peaceful and can be kept as a pair or in schools. Unique among angelfish, those from the genus Genicanthus are zooplanktivores.
