Small white 1 antenna snail

[harsha22]

Hi, can some please tell me if this is a pest? I dont remember adding these. Neither did i add live rock. There could have been eggs on my frags even after cleaning them.
They look like regular snails but just very tiny with a white shell and 1 antenna.

Google collonista snail.

Shape looks more like nassarius, whelk, or dove snail,,, but I won't venture a guess as to which one (or something else).

Experts (not me) would likely have better luck with clearer pictures in a small container of water

Im thinking young trochus or dove snail

I have these too but i am not sure what they are. they first appears for me shortly after adding only cerith, trochus and astrea snails. probably hitchhiked as eggs on frags for me as well. Would love to know what they are!

Look up Nassarius pyrrhus to see if it matches.
