I used to have it in my 80 gallon (well still do) but you won't find it on rocks . Mine only grows on power heads and the overflow because I have 7 emerald crabs that keep it check . If an emerald crab catches your fish it was dead ..lol I do have sps and besides climbing in my birdsnest and stylos I don't really witness them doing any harm to the actual coral . They do however like to bust through cracks and knock stuff that isn't glued or encrusted down yet . Easy trade off for not having to look at it on rockwork . Getting them off in clumps and siphoning also works great
