Pseudotropheus crabro, the bumblebee cichlid Tank size

[ShovelNinja]

Hello Im interested In getting a pair of bumble bee cichlids. The thing I need to know is what the tank size should be when the both of them are fully grown and If they are fine in a tank with just the two of them or should I get more like 4-7 of them?

Crabro is one of the largest, more aggressive mbuna. If I were to try them, I would want atleast a 75 gallon or preferably bigger for a male and atleast 6 females.
