My blennies ignore it and my scopas occasionally takes a nibble. One of the few emeralds I had would nibble to, but none I have had yet really like it.
I have had portions of it die off in ulns conditions but it never fully disappears. I was debating sumping the worst rock for a few months but put it in the low maintenance tank instead.
