What is this coming out of my blue tang?

It is hard to see but on the bottom of my blue tang, there is like stringy stuff almost like it’s intestines or guts are coming out? I tried to get the best pic but he is a fast bugger!

Is it white & stringy like this??

Sorta it’s hard to tell exact color. I took him out and put him in QT. Just trying to figure out what it is possibly.

Looks like partially / undigested hair algae, perhaps?
