I've an 8" Indo in a 100g with 3 bichirs. I'm thinking of adding a small shoal of something as Dither fish. The Indo tends to hide under the filter most of the time. Tried adding a medium sized Oscar to bring it out but it hammered it instead. Thought of Prochilodus or Pink-tailed Chalceus which are avaoilable ay my LFS but read these don't do well in groups. Any ideas?
