I have about 25 juvie African cichlids mixed, zebras, kenyis, fronts, peacocks, haps, 2 plecos, 3 cory cats, and 1 raph cat. Tryin to find the perfect unisect temp that will satify all of them. They are in a 75 gal with plenty of circulation:2 125 AC air pumps. 1 AC70, Emperior 75 with bio wheels, and Marineland 50. Any ideas and comments will help.
