Gotcha. You should take a bigger look at victorians! Some are actually pretty compatible with mbuna! I have some victorians and they did excellent in my tank! Plus many of them are excellently colored! I'm looking at getting another 55 just so i can have a tank for a victorian species! I'd also suggest just looking at cichlid-forum.com at their species profiles, and you can look at mbuna, victoria and many other cichlids and see if there are more you like! Hopefully someone else with more experience with mbuna can chime in too.
So if they are the same size, water parameters, and aggression level, you can mix and match any of the Victoria and Malawi species, or are there still some that can't intermingle?
