Any ideas what's causing the patterning in the algae on my aquarium glass? (sh.itjust.works)

Maybe these are just from snail trails and my snails have OCD?

Your looking at it. It's the snail monchies. If you have algae eating fish in there, same.

Probably from the snails or fish, but it looks kinda like a big fingerprint!
