I recently put 4 peppermint shrimp into my 75. 1 week after when I checked the tank in the am. my white torch coral was down to bare skeleton. In just one night. The next night(after having tested every parameter possible) I used a red flashlight and found the peppermint shrimp feasting on what was left of the torch. I have been spending the last 3 days trying to capture them. I am now using a mantis trap that has caught every single Nassa snail in the tank. No shrimp in the trap. I was finally able to catch 2 of the more agressive shrimp in a clear glass with bait. Is this normal behavior for these shrimp? How can I get the last 2? The two that i did catch practically attacked my hand when I put it near there hole!
