Common hitchhiker snail. They won't grow larger that, and they're good members of your cuc.

Could be a keyhole limpet

Collonista snails… another hitch hiker. These guys are noctural. You’ll see them in the day but check out your tank in the wee hours of the morning. They are everywhere and reproduce well and stay small.
