| || | So you are telling him to keep trying all the fish until you find out? It is obvious that he has an incompatible list of stocks. Why keep trying? The tank size was not mentioned at all yet I see two fishes, the balas and Columbians having the potential to outgrow most home aquaria. I mentioned already that Columbians are the suspects and the balas will count soon enough so there is no point trying. Get rid of these fish immediately and replace them with better ones such as rasboras, corydoras and platies.

As far as the giant danios are concerned, they may get nippy but I doubt they will try to eat guppies.
