I just received an order of trochus snails in the mail. I acclimated them and put them in my tank. First, my cleaner shrimp flipped one and started to pick at it so I shooed him away. He came back again but after the second time of me moving him away, he left them alone, at least for now. Then, my nassarius snails started to attack them. They would flip them over and I’d see the trochus snail’s foot moving trying to get away. After separating a few nassarius snails from the trochus, I placed the trochus snails high up on the rock work to keep them away from the nassarius snails. I’ve never heard of nassarius snails doing this to living snails. Has anyone else had experience with this? If so, any recommendations? Thanks.
