Description: Green Chromide has an olive green to greenish brown body color, with six to eight transverse bars which may at times, be indistinct. Each scale has a golden spot. The anal fin may have some blue iridescence. At spawning, the fish’s colors become more impressive. Juvenile fish have a different coloration than the adults: they have a single transverse band around the mid-section, which disappears, and for several weeks the fry are just silver. Etroplus suratensis can survive in freshwater, but is more susceptible to diseases and often loses its color. Green Chromide is known as a foodfish in India.

It is almost impossible to tell the differences between sexes, except during spawning, when the male’s genital papillae is visible, and it is pointed. Spawning might be induced with a raise in temperature and salinity. The best way to obtain a pair is to purchase a group of 6-8 young fish. When a pair form, they should be bred in a separated tank. The female lays up to 1000 eggs on a previously cleaned rock or in a cave. The eggs hatch in 36-48 hours and are guarded vigorously by both parents. The young are free-swimming after another 7 days. During the first days the fry can often be seen clinging to the flanks of the female, as she produces a nutritious mucous, in a similar fashion to discus. The fry are relatively large, and can be fed with artemia nauplii and powdered dry foods. The fry are very sensitive to water conditions changes, so regular small water changes are best.
