Oto is cleaning the snails' shells

It's interesting to watch; the snails won't retreat back into their shells, but when he gets a little too close to their body they'll twitch. I don't guess there's any harm with the oto doing this?

No worries. Snail shells must be great sources of food, snails do it to each other all the time too.
