african and south american cichlid

Hello! I recently went on a trip to Peru and, while fishing, I caught and released these pike cichlids. I've been trying to identify them and I have a good idea on some of them but I was wondering if anyone could offer any suggestions! Any help would be greatly appreciated!

I have a 75 gallon tank with 2 frontosa's and 2 blood parrot cichlids. Yes, I know that I've mixed African cichlids and South American cichlids together but they get along well. I've recently noticed that the biggest Blood parrot is the king of the tank but not a really good one. I was wondering...
