is a 90-gallon tank suitable for mbuna stock?

Planning a 90-gallon Mbuna tank and considering these four species. Would appreciate advice from experienced mbuna keepers on whether they'll work well together.

Msobo
Demasoni
Tangazo
Yellow Labs

I'd recommend dropping either the Msobo or the Yellow Labs, as they share some similarities. You might encounter some aggression issues between Msobo and Tangazo males, so it's worth considering which one to keep. For what it's worth, I'd suggest going with Demasoni - they do well in large groups, so be prepared for that - Tangazo, and Yellow Labs.

Your species choices are excellent, by the way. I'm actually planning to stock my 120G with a sizable group of two out of those three to start.
