Yea. They were true peppermints. I've kept both peppermints and camel shrimp in the past. I run open top on all of my nanos and my camel shrimp jumped out one night a couple years ago and my japanese red pistol took care of the peppermints after a couple months. I haven't kept any since.You made sure they were true Peps and not Camel Shrimp right? They are often confused and Camels wont touch aiptasia. Peps have always worked for me.
