The Maldives damselfish (Amblyglyphidodon indicus) is a fairly recently described species, having been described by Allen & Randall in 2002. They are not common on the Tanzanian coast but in certain areas there are fair numbers of them.
The body has an oval disc shape with a sharpish nose. The body is distinctively more disc shaped than the other damselfish. The base color of the body is silver with a slight blue tint. The anal and rear dorsal fin are lined with a black stripe and the caudal fin has a black stripe on the upper and lower rays. They grow up to 8 cm in length. The juveniles have a similar coloration but the pectoral fins are yellow.
MALDIVES DAMSELFISH IN THE WILD
They are not common fish on Tanzanian reefs. Usually they are seen on protected and semi protected reefs from 2 meters to a depth of 12 to 18 meters. They appear to be territorial and if one returns to the same spot they will be there. They are always over large thick branched acropora corals and are usually swimming with other fishes that associate with these corals during the day such as the Wolf Cardinalfish, the Tiger Cardinalfish and the Crowned Squirrelfish. Usually there is a fairly large group of them above the coral.
The Maldives Damselfish is found across the West Indian Ocean area from the Indian west coast to the East coast of Africa including the Islands. They are found mainly on semi protected reefs and on shallower protected reefs. They are always over very large acropora corals.
The Maldives Damselfish feed predominantly on zooplankton.
Little if any research has been done on their mating habits, but they probably follow the normal Damselfish behavior. Pairing before mating is usual and after the male cleans a patch for the eggs, mating takes place. The eggs are demersal and adhere to the substrate. The males guard and aerate the eggs until they hatch.
They are hardy fish and would be easy to keep in an aquarium. However they would undoubtedly become highly territorial. It is almost a certainty that they will harass and beat up more peaceful fish.
