I’ve had this snail in my reef since I got it thought nothing of it. I noticed that there have been some snails appearing. I don’t know if they are from this snail, baby astrea snails or if they are pests from a recent purchase of astrea snails. Does anyone know the id of this snail and wether the baby is a astrea snail a pest or the snails baby

Pictures are a little blurry, but here are my guesses:

The large snail looks like a marine nerite snail, a popular algae-grazer:

The little snail on the bottom looks like a dove snail (Columbellidae sp.), a hitchhiking, algae-grazing snail that is desirable for its small size (can reach crevices and macroalgae fronds), and for being a prolific breeder:

I think it might be collonista snails because of the shape. I got some better pictures so hopefully they will help.

These are definitely Collonista snails. I just thought I saw a large siphon on the small snail in the first picture (which are characteristic of Dove snails).
