But *** had convicts before in my moms 120 gallon tank. They breed fast. But the tank is in the philippines. I live here in Cali now. Im thinking of having 2-3 kenyi's in my 20gallon. Why is it more difficult to care for a kenyi than a convict? *** had kenyis a long time ago and im fascinated with its behaviour specially at in the dark. Anybody out there please respond.
