what is a promising bait some of you have had success in baiting your mantis traps with?....mine won't come out for raw shrimp....also, since there are so many crabs and snails in my tank, i really can't starve him...any advice not involving rock removal, freshwater dips, or predators? i want to keep this guy (he's amazing) not murder him, just need him in another tank, which is not big enough to replace the rock he is in into...thanks!
