I guess one thing that I forgot to ask you Joe is; what temp. is good for Discus? Right now my tank is at 85F. I plan to get some cardinals, ottos, corys and rams but Im worried about the high temp. My lfs mentioned that the temp is a little too high and I dont need it that high especially if I want to place other fish in. Should I keep the temp at 85F or lower it to 80F? Would it be ok for the other fish in such high temp?
