Cool.. Got a clown in the tank? Our Clarkii took right to our new BTA, maybe a day. Good luck. Ours was maybe 3" when we placed him, but now its probably about 6" and seems to be getting bigger. I'd say we've had it a month, maybe a little more.
I have a pair of true percs. They dont go near my green BTA because its very small and i dont think they want a small anemone. So i got the Rose BTA which is about 8 inches across tonight will be its first night in the tank so I hope they take to it
