I have two African Dwarf Frogs in a 10 gallon tank and they leave a lot of blood worms and flakes left over (mainly because they can't find them) on the bottom. I wanted to get a plecostomus eventually, but I find they ignore a lot of the "leftovers" when I've had them before, so I was thinking a small catfish. Then maybe a couple of non-bottom-feeding fish later on. Anway, I have had a 10 gallon tank before with a couple of gouramis, a catfish, and a plecostomus, but I'm worried with the ADFs, that 4 bottom feeders in a 10 gallon tank is too much. Any suggestions?
