Hi, I just found this fourm. I have had a snail for about a month and a 1/2. I have no idea what kind of snail he is, or if I am supposed to be feeding him? I thought he would just eat algae, but then i read on this site that only certin snail do that.

How do i figure out what kind of snail he is, and if/what i should feed him?
Buster is my snail's name. He is maybe half the size of a golf ball. His shell changes color sometimes it's dark blueish green, sometimes it's more yellow/brown.
Can anyone help?
