Anyone else have hermit crabs that push everything over? It is starting to irratate me. It wasn't that bad before but now that I have a bunch of small frags it is everyday.

My wife wants me to ban them all to the sump, but then I wouldn't have anything to stir up my crushed coral gravel.

Anyone have any ideas? Is there something else I can use to turn the substrait that won't climb all over the rocks knocking stuff over?
