First time posting... Thanks for viewing.

My polyps are normally very healthy and growing at an alarming rate, but then about a month ago I got this small bald spot but didn't think much of it. Now it seems to be growing quickly and seems to be killing my polyps from the inside out. Any ideas on what this is? Is this normal or do i need to treat it? Please advise on a course of action.

Thanks.

First welcome to R2R!
If you see it taking over your GSP's I would cut it out. You won't hurt them one bit.
You have some nice colonies of them!
Maybe a mod can move this for us :-)
