I have had these growing in my overflow and sump for a while now. Noticed a couple now growing on the sand. Thanks in advance.

Sorry to bomb your post but i was just about to ask this question about these i found growing in the lower flow areas of my tank
Is this the same thing?

Kind of looks the same. Hard to tell. I have a lot of them clustered together in groups. Yours looks like a single specimen so could be something different.
