I bought some peppermint shrimp today and they got annihilated by my wrasse's and my anemone sucked one right down, bought 6 only 1 Survivor left buying the wand tomorrow and Aiptasia X
IMO you were fortunate your wrasse got to them. In my experience peppermint shrimp are some of the most opportunistic feeders I've ever seen. I have personally seen them pick at a coral until it dies. I've seen them attack sleeping or weak fish and kill them. IMO adding just one peppermint shrimp to any tank is a mistake. I believe they are the devil in disguise. YMMV
