Tropeus Duboisi & Peacock

I'm setting up 125 gallon cichlid tank mostly peacocks and a couple electric yellow mbuna. I like the Tropeus Duboisi cichlid that is black with the white spots but it comes from a different lake in Africa. Does anyone have any experience mixing that with a peacock? I'm wondering if I will have issues with aggression or should I say extra aggression with fish from these two different lakes

 

Tropheus need large groups, and the white spots indicate a juvenile T. duboisi. As adults they are black with a white or yellow bar in the middle of the body and get over 5 inches. I would not mix them with Malawian species. Aggression is a definite risk, and required water parameters are quite different.

 

If the peacocks are bigger than T. duboisi then it would probably work. T. duboisi would try to push the peacocks around but they wouldn't allow him and they would sort of work it out. But if they are of the same size, I would expect that T. duboisi would terrorize the peacocks to death - chase them down and kill them. I have seen them together I recall, but always with big peacocks that are tough big boys. They don't kill by attacking, its more of a wear out the little guy by chasing him around. If they aren't afraid, then they don't run away.

Have a back up plan for what to do if you have to take him out. He is a semi-endangered species.

 

There is another reason not to combine the two, which I forgot to mention before. Tropheus are strict vegetarians, and any meat protein in their diet often causes bloat or other illnesses. Peacocks are not vegetarians, and require some meaty diet. Trying to feed the two in the same tank is a logistical nightmare, and invariably fails.

I have also seen them kept in the same tank, mostly at stores, where neither one is intended to be there permanently. Long term, those fish will not co-exists for a multitude of reasons.

Absolutely agree, lost half a colony of Tropheus moorii (species tank) because I accidently gave them frozen brineshrimp. Bloodworms would have killed the whole colony.
