I have a 10 gallon planted tank that looks great, thanks to most of the people on this list. It occupies 7 Cardinals, and 3 Oto catfish. The filtration is a small whisper PF. Should I stop there since I do want a low stocking level, or should I add a few more cardinals? a RAM? I should probably stop, just want some opinions.
