Are these zoa eating snails?

[noahreefer]

Hello all,

recently did a dip on one of my zoas and found this snail on it. Could this be a zoa eating snail?

collonista snails, they are beneficial but can grow to large populations. they like to get sucked into my mp10s

Never heard of a zoa eating snail but these guys are found everywhere and multiply like mice !

Sundial snails are predatory to zoas. Never had them though.

Definitely a collonista, sundial are more flat in apperance and has an unmistakable trap door.

I looked up some pics of Collonista snails and it looked pretty exact to the one I found.
