By red pike it could also be a crenicichla xingu II one of my favs. They are hot but as said make sure they are well cared for and do not have HITH. Knowing what kind of Satanoperca you keep (very prone to HITH) I have no doubt you would be caring for the pikes well bro, they are lucky to be with you if you go through with it. I would take a good pike over a clown loach(s) and/or clown pleco(s) any day.
