Has anyone kept these in a mixed SA tank? I have a 125 gal. 6' tank with a small group of Geophagus, a single Severum, a single Heckeli and a pair of Aequidens metae. There is also a small chocolate cichlid that may move out. I think it may be too similar and too big to work with the Paratilapia long term I was considering keeping a single Paratilapia. I keep the tank at 80-81 degrees and do a 40-50% water change weekly. Any thoughts? Thank you!
