Well, I wish I could take credit for the Florida Flag Fish idea, but I actually got it from cpr4cpu. Anyway, I have two males and they have done wonderfully in a community tank. I also have 4 buenos aires tetras, 3 scissortail rasboras, and 5 ottos in the tank. Never had any territorial or aggression problems between any of the tankmates and the FFF. In fact they play quite often with the others.
By the way, Sumpin'fishy - my FFF have mowed the hair algae to nothing. Now I feed them flake food, freeze-dried bloodworms, frozen brine shrimp, and they nibble on the algae tablets I put in for the ottos. I wouldn't worry about what to feed them - it seems that they'll eat just about anything and love every second of it!
