Just got a 3" maroon/yellow clown, and was thinking of getting him a BTA down the road. How big should the BTA be for this size clown? I've heard if you get one too small, the clown will just tear it up before it gets established.
For a maroon at least twice the clowns size, the bigger the better and I would try to keep the clown away while the anemome finds a spot, sometimes maroons beat them all over the tank and don't give them a chance.
I dont keep maroons, but I do know thatthey can be brutal on anemones. Many people recommend an anemone 3X the sixe of the clown. I agree with Petjunkie.. Go at least 2x as large
