Introduction
Normally gray-blue with iridescences , the variable colors of this fish take on delicate pastel blue luster under side lighting and especially when spawning .Two thin gold lines run back from the dark-centered , gold-rimmed eye to the end of the caudal peduncle.Fins are generally translucent green, but some may show yellow shading.Sexual difference in this species include more intense colors in the male and a deeper female body.

Blue Danio , Kerr's Danio
Species
Brachydanio kerri
Habitat
Streams on island in the Bay of Bengal off the west coast of Thailand.

Minimum Tank Size
A standard 24" x 15" x 12"/60cm x 37.5cm x 30cm/70.8 litre tank is big enough to house a group.
Diet
Stomach analyses of wild specimens have revealed this species to be chiefly insectivorous, feeding on a variety of aquatic/terrestrial insects and their larvae.A good quality dried product can be used as the staple diet but this should be supplemented with regular meals of small live and frozen fare such as bloodworm, Daphnia, Artemia, etc. for the fish to develop the best colouration and conditioning.
