considering removing hermits

[bignose]

I've had enough with hermit crabs and I'm ready to get rid of them. They constantly kill my snails and often kill each other. Knock my frags off my rack and mow over all my corals when I feed the fish. The last straw was when they killed my conch.

I'm ready to rid my tank of these pests but I have one question. Can I run my tank with just snails? Any other input is appreciated.
