Help identifying snails

[MelancholyBlenny]

Have a bunch of these snails in my dads tank, more in the sump than in the dt but definitely some in the dt as well. They dont seem to be harming anything but I'm curious what type of snail they are. Been searching but couldn't find anything that looks exactly like it. The brown and white ones not the limpets.

Probably Collonista snails.

Was looking at those and nerite but the pictures i found online didnt match exactly so i wasnt sure. Appreciate the input!

Those are trochus snails. I have a bunch of 'em in my tank too.

I think Collonista snails.
I had a ton of them....they get into pumps ...
I manually removed hundreds at nighttime to cull the population
