I just bought a blue balloon ram the other day (or a deformed GBR as I later found out).

I would like to add one or two more rams to my tank to make it complete. I know that they are territorial and am thinking maybe just one more would be enough. I have a lot of plants for them to hide in, a piece of driftwood that forms a cave and a cave I made from rocks. (My pictus cats are currently camped in the rock cave). No one is currently calling the driftwood home.

Would a Bolivian be more apt to have issues with my current ram or should I just get another GBR or two? What about sexing?

Any recommendations / advice?
