Frag rack care

[jason604]

Man I'm getting really really annoyed and need tips to how ppl keep their frag rack full when they wake up in the morning!!! Every morning I wake up to many many fallen frag plugs from my rack(egg crates) due to those damn snails climbing in it and just knocking everything down. Or somehow my GIANT red scarlet hermit climbs my sps like spider man n reach over to my rack which is at least 3" away from anything. I know I (may) be able to move the rack farther so crab can't super reach it but what do I do about the snails?
