I agree about getting rid of the bumble bees from what I've heard alot of people say about them. I also agree that one brichardi should be ok from what I've heard others say about them too.
I had 2 small brichardi in my 55g. tank with alot of other fish that was mostly malawi mbuna. At first they didn't act like they liked each other much and I was afraid one might kill the other eventually because if they don't pair up that's usually what happens but then they started acting like they liked each other so I got a 29g. tank for them and was planning to start a colony of them in the 29g. but before I got them in it, I had an accident with my heater and lost one of them .
I have a brichardi colony with mbuna. Brichardi can really hold their own, and I even have very young brichardi fry in the tank. I have been advised to move the mbuna out of the tank by my LFS becuase they will cause terror, however, I haven't seen it yet. I have 4 mbuna in my "all tang tank." They are now preparing to mate, and they still haven't bothered the brichardi. :wink: Go for it!
youngb074, what size tank is it that you have the brichardi colony in with mbuna? I was under the impression that unless it was a very big tank, the brichardi would terrorize the mbuna when they (the brichardi) started to breed.
