I guess Im the ecception to the rule then, Ive always kept Peppermint shrimp with absolutely zero problems, in fact, I wouldnt be without them in my reef... They do a great job of controlling Aiptasia and are very entertaining. Ive yet to witness them being the merciless killers theyve been made out to be. No thanks, Ill keep my peps! Just make sure what you have is in fact Peppermint shrimp.
