[Son Of Skyline]

Has anybody ever tried a crab only cleanup crew? I seem to be having problems keeping snails alive. For every 10 snails I introduce to the tank only 2-4 survive. I'm familiar with acclimation methods and all that, and water quality is spot on. My fish, corals, urchin, crabs..etc don't have this problem.

So I'm wondering if anyone's ever used crabs and no snails. I'm getting tired of wasting money on snail shells. Success stories? Horror stories? Thanks in advance.
