Okay, so currently in what will soon be a fairly heavily planted 50 gallon tank are 3 yo yo loaches, a bristlenose pleco, and seven zebra danios. Filtration is a Filstar XP2 and an Emperor 280. If I was to add a pair of dwarf cockatoo cichlids, would there be room still for 3 upsidedown catfish without this being overstocked? Right now the tank seems fairly empty, and the loaches won't get that much bigger than they are.
If the catfish won't work for whatever reason, what else might you suggest for mid/top levels of the aquarium?
