Does anyone have any tips on how I can catch my pistol shrimp out of my tank without dismantling it? I have already tried the water bottle trap method, he seems to be interested in it but never actually makes it all the way into the trap. Also the place where I have to place the trap is very cramped and it is hard for me to snatch it up quickly even if he were to go in. Plus my nassarius snails always make it into the trap before the shrimp does and that discourages him from comming in. So any other tips on catching these things would be very appreciated, tired of waking up to a rearranged sand bed and corals completely covered in sand.
