Hi.. I have a pair of breeding clowns in my display tank, but a large crab has found an appetite for the eggs. Pretty frustrating. I have no hope of catching the crab as there is no way I'm about tare down my entire reef, so I'm hoping I could catch the breeding pair and put them in their own tank. I wouldn't mind buying a trap online for the $55, but it sounds like people have gotten mixed results using them, and its kind of steep to shell out the $55 just to find out I wasted my money. Any help?
