OK. I have a 55 gallon tank that is a newer set up. I have one Synodontis eupterus, 3 peacock cichlids, and 1 rubber lipped pleco in it. My brother had just a common pleco and another Synodontis eupterus in a 38 gallon tank... his broke so i put his fish in my tank for now... both Synodontis eupterus are about 3 inches long... will they be ok together for a couple days... or until whenever he can get a new tank?! HELP PLEASE!!!
