Do these snails get bigger

[jeffrey750750]

There has to be hundreds of them. Don't know if they came in on the live rock or from various snails purchased

If those are Collonista snails they only get to be about a 1/2" in diameter. They probably came in on your live rock. Just a harmless grazer.

I've seen quite a bit of them on a daily basis but I was up at 4am and the tank was loaded like I've never seen before. It was amusing to say the least

Yeah, I used to have them in my tank too. They were always out in full force when the lights were off. If you have a LFS that's close you might want to remove a dozen or so every now and then and give them away. Either to a fellow hobbyist or the store itself. GL.
