No I haven't. Look up some past threads on the subject. There are quite a few shrimp that look like peppermints that will eat coral. Surprised to hear the nem didn't get him first!Have you ever had issues with them eating zoas or any other corals or nems? I have some pricey zoa specimens I’d rather not turn into shrimp food… My last attempt at using husbandry against aiptasia was a filefish and it was a smashing success until the aiptasia were gone. Then he ate half my RBTA’s foot, eventually killing it and decimated a couple zoa colonies. So I’m a bit gun-shy.
