Blasto coral pooping or stressed?

[fishmonkey]

So I just did a major cleaning and 10% water change in my tank. My blasto is emitting this stringy thing from the main head. I never seen it do that and was wondering if it was stressed or pooping. It ate some Mysis probably 2 days ago.

I'm going with poop for $200 Alex.

Agree. Blasting is taking a dump. Give him some privacy man. :)

It’s just I never seen it do that and it happened in a somewhat stressful event of cleaning lots of cyano. I also think I moved it around once
