Considering that a bp is a crossbreed of one of the most peaceful sa cichlids the Severum, and one of the most aggressive the red
Devil. It makes the fish Bert compatible in my opinion. Many disagree and say it's very incompatible. But with that fish I would recommend, most community fish that can't fit in it's mouth, you could have an oscar, a Severum, a jd could work, I've also seen parrots with African cichlids, not to sure if that's the best idea, but the PH could work aggression on the other hand could be a problem.
