WTT: 2 or 3 hermit crabs for few snails

[akma]

I have 2 or 3 hermit crabs in my tank I would like to trade for a few snails(turbo, nassarius, cerith, etc). Or if you can't spare a few you can have the hermit crabs for few. Just want to keep my tank with snails only. There are supposed to be 2 dwarf zebra hermits
