90 gallon question

[Firecracker]

I currently have a 50g set-up with a mating trio of brichardi (and a generation or two of their young ones).
I plan to move to a 90g. My question is... with the 90g tank, will I be able to put another species in also instead of just the brichardi? I knew that it would have to be a brichardi only tank with the 55g, but would 90g be large enough to add some lelupi or tropheus (or something) in there with them?

probably not .... not at the rate brichardis breed and how aggresive they become while doing so you would be better off leaving them in their current tank and setting up the 90 with whatever else you want.
