So for some reason in my tank my trochus snails have a luxurious fuzz of algae on their shells. They look like white snake. There’s algae here and there around the tank but not a bothersome amount. Recently I discovered a single asterina star that’s I keep a vet close eye on. Today I found the star riding on the snails shell. So I’m not sure if the star is eating algae off the snail or if he means him harm. Any ideas?
