I'm thinking of starting a cichlid tank, but i also want to through some semi aggressive fish in with them. I would probably end up putting in some fresh water sharks and possibly some larger clown leaches. What do you think about mixing tropicals with cichlids? Does anyone have any suggestions or mixed tanks that worked for them? If I do mix fish I would probably mix them as juveniles so they all grow at the same rate so there are not any fish that are too small that might get picked on or even eaten. Please tell me what you think.
