I found this small snail in my tank today. Can anyone tell me if it is friend or foe and what it is? Thanks

Looks like a Collonista snail, they like to come out at night and eat algae

yes it is a collonista there are two in my tank that came on a piece of LR i got. very harmless and ive only ever seen them in the shadows of my tank or at night when i look in with a flashlight.

Do they eat coraline algae too, I think I have some of those in my tank and I'm seeing white spots on my rocks, looks like somethings been munching on my coraline.
