Abstract
 
The breeding biology and larval development of Angelfish have been described. There are few secondary sexual differences in immature fish. In the adult, the head of the male is convex and when viewed head on, the abdomen of the male appears concave while it is convex in the female. The taxonomic status of the genus has been discussed. The spawning behaviour of this species is quite elaborate. About 350 to l300 eggs are laid at each spawning and the eggs take about 2 to 3 days to hatch. The larvae become free swimming within 3 to 4 days. The larva resembles the adult in a period of about one month. A brief note on the breeding technique and management of Angelfish has been given.
