Never heard much of this from this specific type of tang so I was just wondering if any of you ever had any Acanthurus tangs eat coral. I first noticed when moving corals from the sand to new rocks due to a court jester goby that kept burying them. I watched the gold rim rip two heads off the acan and spit them out. I thought maybe this was just from me moving them and that this was new behavior but I also caught him picking at the gonipora that had been closed up for a while. I started watching everyday and realized the gonipora is open a little at night but then as soon as the lights come on he picks at it and it stays closed the entire day. Seems like he picks enough to not rip lots of flesh off but it’s enough for the goniopora to never open when the lights are on. For months I had thought it was just being bothered by the occasional sand the goby would put on it but this may have been happening for a long time. Now today I have watched him closer and have seen him pick at the tips of multiple acropora. Most of the ones he is picking at have white tips which I had figured maybe just had been caused by some swing in parameters or my nutrients staying too low but then I noticed my digitata has the tips ripped up and one atomik humilis just has some tears on the tips which I also noticed a few weeks ago but had since healed. Those two corals lead me to believe that he is definitely picking at sps corals that are healthy and not just picking algae off of tips that are already dead.
