What is this white thing on the acro?

Are you able to get a bit closer with your camera? Some of the lower branches look like bite marks from acro eating flatworms- if you look closely, does it look like this where there is sporadic white?

Thank god it looks different. A friend of mine told me it is high likely gorilla crap bites.

Am not sure how on the earth he will reach the tank with all the precautions I do before adding any corals to the tank!! Assuming he is there now.

Sorry, is this coral in the tank currently, or your saying it's a piece you'll be placing into your tank (after you dip)?

While it's possible that it's damage from a gorilla crab, I can't quite see enough from the picture to comment one way or another. That being said, the few SPS I've seen affected by gorilla crabs tended to have damage in a pretty consistent and linear fashion (the crab would sit at the base/stalk and just pick at the coral). Your damage looks pretty widespread and pocketed. If you can grab another picture, it might help.

Also, is this going immediately in your DT after the dip or into a QT?

Unfortunately it is in the DT. I don't have QT.

Shall I throw it away?

This coral in the tank for more than 6 months. Doing good during day time with decent PE.

That’s odd. Definitely looks like something is eating it, perfectly circular recession doesn’t happen.

Are any other corals affected? I wouldn't toss it necessarily. Any chance you could get a closer photo? How large is the tank and do you have any wrasses in it? If you look closely, do you see any small eggs? When you say it looks different then the photo, how so?
