Snail identification?

[Starfish12g]

Hey I've had these snails in my tank for almost a year now and they exploded in numbers. They reproduced at least twice in large numbers and now have well over 100+. Just wondering what they are, they seem to be pretty slow growers and typically only come out at night. They were hitchhikers on some live rock.

Looks like a nerite snail to me. Good algae eaters.

Max size of collonista snails is 1/4” isn't it?

If im not mistaken nerite need freshwater in order to breed. I wouldn't think these are nerite.
