Noticed this on the glass today? Pics are not the best but it doesn’t look like a algae of any sort to me?

Looks like coralline algae!

If it doesn't move, it's coralline algae. Good stuff. Coats your rocks in pinks and purples and reds and outcompetes things like hair algae for space. Corals will adhere to it better as well and it generally looks better than green fuzz. Only annoying when it covers the glass.
