Rainbow Acan throwing up!?

[MTsquared]

Just saw this happening on a rainbow acan in my tank. I’ve seen LPS “throw up” their guts before but this doesn’t look like that. Curious if anyone can help? Only seems to be coming from the one polyp the rest of the colony appears to be fine and healthy. The other acan in the tank appear to be fine. Thanks in advance.

Could it be a digested pieces of food?

Interesting.. I have seen my Acans do something similar but never that large. No effect on them after.

Not sure if it was food or not. Continuing to monitor the situation however, it looked fine today.

I have heard that if they take in to much food they will regurgitate some of it, maybe to much or to big pieces of food.
