Black spots on toadstoolpolyps

Hello,

What are these black spots on my toadstool (on the polyps)?

It is in a high flow area. Maybe too much flow?
Thx in advance!

Interesting, but I don't believe anything is wrong. It looks healthy

May be infected tissue often caused by raising the intensity of light or installing a different light.
Did you by chance?

If this continues, you may have to dip it.

No, didn't change anything on my light for the last 2 weeks. Only switched of my light 2 days ago for a few hours when introducing my foxface.
