I just recently bought a Gold Nugget Pleco and did a little more reading on him to see if there is anything different needed compared to my other fish in the tank as far as special needs. At thatfishplace.com, in thier section for care they mention that the pleco is sensitive to temp. My tank is currenly at 74 degrees and has had no problems with any of the other fish (Gars, crayfish, raphael, crabs, and a softshell turtle), should I turn up the heat? or do you think the little guy will be fine?
