lucky you. i had a striated bristletooth tang that i had to remove from mine. he was a great fish and he kept the rocks spotless, but out of the blue after about five yrs of perfect behavour he started to chase all my little fish. lost a couple from stress, wouldnt come out and eat. he didnt bother the other tangs though. complete teardown to catch him. what a pain in the butt. i want to replace him with a yellow eye kole tang, same as you got. the bristletooths are great fish. they never stop scrubbing the rocks
