I have a species in the same genus, but native to the USA. I feed him regular tropical fish flakes, mostly. Sometimes I give Tetra reptile pellets, or such, to vary the diet. He is healthy and has always been among the most active members of my invert tank. It is heavily planted, and I have some big rocks from the local river, so there are places to hide. I keep the water parameters about what is normally suggested for tropical fish. I heartily recommend cambarellus. They are fun little guys to watch.
