fuzzy algae on snail's shell

[ALang]

Nah, I'd say leave it alone, scrubbing the shell will still leave stubble and it'll grow back anyway. My snails just clean each other when they happen to meet. Sometimes that won't happen for a while, and other times, they'll congregate in a spot to do each other a favour.

Yup just leave him be. Any other algea eaters in the tank will remove as Lenny said.
