White trails on rock?

Doobie65 · Jul 25, 2020

Im noticing these white trails on my rock lately and I dont think snails are doing this. Anyone have any idea? If so, is it a good or bad thing?

somthing is just cleaning them off. no worries my snails do this all the time eventually theyll be clean and white everywhere at least untill the coraline algae takes over

My urchin will leave clean trails on my rock, it’s really noticeable under the blue lights, clean trails through the coralline.

Wow! Thats pretty powerful to just strip the coraline! I dont have any coraline yet. If its the urchin doing this then its totally at night because he is ALWAYS in the same spot when lights are on.
