Snail eating my acrylic

[SCUBA PETE]

keep getting these crazy patterns on my acrylic that appear to be from snail. have no clue which snail it is, or i'd obviously i'd remove him. have googled it and can't find anything. Any one know anything about it or how to stop it? i have a 360 gallon tank and likely 70+ snails so removing all of them will be very difficult.

I would guess the snails are eating the algae growing on the surface of the acylic. Clean the surface of the algea and perhaps it will go away. If not remove the snails teeth. j/k.lol

+1 there is probably a thin film of algae on the acrylic and the snails are eating some of it leaving a squiggly line or some other pattern where they at it. This happens in my biocube all the time.
