I have a 120 gallon lake Malawi tank. I purchased this tank used. It has a school of 11giant danios and 1 beautiful Sail fin pleco. The former owner already had the Ph setup for the syno catfish. I have since stocked the tank with mbuna. My question is though the water Parameters have not yet hurt the pleco should I look to my aquarium club for a possible relocate of my pleco?
