[Key Equine]

I had a few that my peppermint shrimp didn't eat, so I took a lighter to them until they were good and melted, then rinsed and brushed away the remnants with a toothbrush. When I put the rocks back in the tank, my peppermint shrimp went right to where I had burned the aiptasia and picked out whatever was left in the hole. It was very cool and worked like a charm. Never saw another sign of them...
