I recently bought 40 lb of LR in addition to my 200lb of LR. This morning I heard a clik clik sound and I saw a 2" green mantis shrimp hiding in my foundation rock!! I certainly can't take my base rock out, I'll have to move all my rocks to do that. Could someone help me how to make a trap for this shrimp. Do they prey at night? what's the best bait to catch them. I have lots of shrimps and snails in my tank and I need to get rid of it asap.
