Ok i have 2 peppermint shrimp that ive had for about a month now to rid my tank of aiptasia. They did a good job killing all of the aiptasia but i have had 3 snails die since i put them in there. My snails climb up the glass and fall off onto their backs quite frequently and one day i saw one flipped over with a peppermint shrimp on top picking it clean. I took the snail out and its shell was completely empty. Do you think it is the shrimp doing this or something else cause i also have a mexican turbo that never flips over and he is fine????
