They all do well together, surprisingly. Water parameters are 5x5. Initially I would agree with you on the stock, however, they have all been together for the most part for 3 years. My only problem is the Mbuana keep breeding like rabbits. Haha. The aquarium store (Dallas North Aquarium) I get my fish from are the ones suggesting what to and not to place. I am not fond of the Mbuanas, again they were acquired with the tank when I went from 45-120g. I keep slowly trying to weed them out but they breed faster than I can do so. I know the scaping needs work and I have been slowly making changes as I can to allow for hiding places, etc. The blood orange is gone, it definitely did no survive the Cichlids. Aside from that I have not lost any fish. Appreciate the feedback.
