What’s going on with my Acan

[LIreefguy]

What are those white things that look like it’s coming out of my acan echanata . Lights were off
And there isn’t a coral close it to

 

[T-J]

There's something on that rock that it feels is a threat. That's what it looks like when Acans attack.

As stated above, likely what you're seeing.

That’s weird I don’t see anything on the rock
Must be a sponge or something

I will say acan pretty much win the battle with most corals
This guy has damaged my raja rampage chalice that feel on it, my basto and it feel on my acan bowabaki and won that one too
