I've had good luck with peppermints from the Keys too - I've heard that you want to try to get the ones from the Gulf of Mexico side of Florida since they're more likely to have grown up on aiptasia. I usually recommend captive bred anything over wild caught, but for this purpose I'd probably stay away from captive bred unless they were raised on aiptaisa.I’ve had good luck with the peppermints that my LFS gets in from the keys.
