Green Chromide
Etroplus suratensis
Brackish South Asia Usually captive bred
One of the few cichlids native to Asia, this disc-shaped fish thrives best in brackish aquaria. It is gentle, shoaling, and mostly herbivorous, frequently grazing on macroalgae and vegetable fare. Keep it in a sizable group with peaceful brackish tank mates like scats and monos.
Also called: Pearlspot, Banded etroplus, Banded pearlspot, Green chromide.

Diet and tank layout
Green Chromide is an omnivore that swims in the middle of the tank. It eats or uproots plants, so choose hard-leaved species or none. Give it some cover. It digs, so anchor plants and keep hard rock off loose sand.
