I found this funny, so I thought I'd share. I have a pair of tomatoe clowns. The female has claimed the BTA and that corner of the tank. I've been surprised that she has no problem with a yellow tang that is often in her corner. I had a small piece of a kenya tree and placed it in the crevice of a rock that back behind the BTA. The next morning I found it loose it the tank, and couldn't figure out how that happened. I placed it back in the same spot and then watched the female clown race right over pick it out of the rock and spit it across the tank.
Needless to say the kenya was re-located to the other end of the tank.
