baby snails

Any of you experience a snail bloom b4? About 4 years ago I noticed There were thousands of barely visible snails in one of my tanks.These snails are now about 3/8" big. They are white and brown and seem to outcompete the little 6 legged starfish that used to be the cleanup crew. Any ideas?

Can we get a pic? or can you find a pic online of them ?

Maybe collinista snails, I spelled that totally wrong but they are small and reproduce like mad from what I've heard. Algea eaters so nothing to worry about.

I was gonna take a pic but did a search on the snails you mentioned and thats the ones.Thanks

I have tons of baby snails and the big ones are constantly messing up my glass with eggs!

I agree I have had tons of them before my tank decided it wanted to grow bad things and most of them died. Still have some tho.
