Here one of my Bottomfeeders checks out the new Snail in town

A snail in my 10 gallon tank.

One yellow, one black.

big snail

My little tank on my desk. I love it so much. currently, I add three beehorn snails to clean the algae on the tank. It workd great.

Tiny brown snail with no operculum, left hand twisted shell, and conical shape. I think it is in the Physidae family, Physa species. I would like to know what it eats and what will eat it.

Is this snail harmful to my plants?
