Is this a disease?

[Zach W]

Hi all, so I’ve noticed that when I feed one of my acans, these white stringy things come out after. Usually they are not present and the coral shows no signs of being sick and is even growing many baby heads. Any ideas what this is?

That’s it’s filaments.
If the coral is happy and growing new
heads..nothing to worry about.
