Acro expelling zooxanthellae?

[Yasha Hase]

Is that what's happening here is that bad or good? Will this help it color up from it's current brown? Sorry for all the questions I've got a fairly new tank about 3 months since the cycle ended that seems to be doing well noticed one of my acros doing this after I fed the tank mysis. Any info would be great!

Feeder tentacles. Normal and nothing to worry about. Some SPS do this. I have a number that does to some degree or another. Light, nutrients, and trace elements generally dictate coloration with light being, IMO, the most influential.

Not expelling zooxanthellae, responding to the food in the tank. Those are feeder tentacles.
