Brown mucus on GSP

Theulli · Mar 7, 2021

Hello!

Woke up this morning and found that my new (2 day old) GSP had developed a big patch of brown mucus overnight. It wasn't algae, it moved with the water flow. The GSP hasn't come out since I put it in the tank. Is this surprising GSP behavior? Do they ever produce their own mucus? Or should I be attacking this like it's brown slime disease?

I have increased the water flow in the tank because I think it was too low, so maybe that'll help. GSP seemed to start poking out a bit more after that...might be my imagination.

Thanks!

What other corals are in the aquarium any LPS corals? They can put out a brown discharge that may have settled on the GSP.

I do have, for example, a candy cane coral. I got rid of the stuff, but it seems to be developing again, but quite slowly this time. Was also thinking that maybe some flake food got stuck on it, it was pretty shocking that it appeared overnight.

Anyway, I think I'm in wait and see mode at the moment on the brown stuff. Now I just need to figure out why the polyps aren't coming out.
