I have 2 Ocellaris and 2 pink skunk clowns. Last month I picked up 2 BTAs for a good price (they were bleaching) at a LFS. 1 BTA went behind my rocks and just seemed to hide. He had NO interaction with the clowns at all. The other BTA tried to commit suicide with my PH (got sucked into the crack between the Ph and the base, this is after I wrapped it in filter material). The net result is that 1 month later I now have 1 unhealthy almost ghostly BTA that still hides in the back of my tank. As well as 1 medium and 2 small healthy BTAs that my Pink skunks have mostly claimed. But trust me, my pair of ocellaris try to claim them occasionally.
In retrospect, I should have made that shorter. So in a nutshell...
At least my Ocelarris like BTAs.
