Tank Mate for Electric Blue Johanni?

[whitexboii]

I need a tank mate for this fish. Just one though, i only want two fish in this tank so the size of the tank is kind of irrelevent because there will be plenty of space.
Also how big does this fish grow? i was told 6 or 7 inches, just want to make sure that is correct

How big is the tank? If you have only two mbuna, youll end up with one before long.

I just purchased an electric blue johanni for my 75 gallon freshwater aquarium. From the research ive done they do grow about 6-7 inches in length, if overfed and given adequate room ive seen rare occasions of almost 10 inches. Currently I have a jack dempsy, blood red parrot, red tiger oscar and the electric blue in the same tank and all seems well. The electric blue is very territorial but everyone seems to comply alright haha. It really depends on the fish and its temperment towards other species. Buying young and similarly sized helps.
