If my peppermint is still alive in my nano when I get back home your more than welcome to take it. It for sure eats them. Disclaimer tho peppermints cqn take to corals so yeah your own risk hehe
I had 5 aiptasias in my tank last week, and I got a pepermenint from Coral Gazers last Friday. Now I don't see any aistapsia in my tank where I saw them before.
