My LFS sold me a clown pleco as a perfect tank mate to my tiny oranda and calico. However I'm looking at the temp specs for the clown pleco and it looks like the water might be a little cold for him -- can anyone comment?
68 is too cold for a Clown Pleco. They shouldn’t be kept in temperatures under 75 or thereabouts. A better choice would be a Rubbernose Pleco or a Hillstream Loach.
