I was wondering - other than the obvious plecs, corys and brochis - what other SA catfish are suited to a community aquarium where the smallest fish are penguin tetras?
Banjo catfish, Hoplosternum speces, Dianema species, the very small Auchenipterids such as Tatia galaxia and Tatia creutzbergi. With tetras you are really quite limited as even the smallest pims, psuedo pims and Doradids will eat them and almost all of the medium sized species of any family aside the ones listed will as well.
