Is this normal for a acan?

[thisguy1]

So I noticed one of my acan corals mouth was wide open with whit stringy things coming out. I was wondering if this was normal or if anyone has seen this before

Don't put your finger in there. Those acans will bite the end of your fingertip off in a NY second
