I recently rescued, yes I say rescued 1 bn pleco, 1 synodontis zebra hybrid catfish and 2 unknown African cichlids. The tank and fish were bought on a buy sell trade site that mother in law shops on. They came with the 75 gal tank along with the canister filter and everything. They weren't in the best of shape and my husband and I are doing everything we can and their health is greatly improving. ( We will be removing the bn pleco cause he and the catfish don't get along at all, don't know how they were together for as long as the guy said he had them) I just need some help identifying what kind of cichlids they are exactly and if possible gender. (These guys seem to like when the air stone is on full blast)
