We had "peppermint" shrimp in the 90. Caught the little *bad word that starts with an F* eating my ACANS! Yeah, never again! Apparently, there are different kinds of "peppermint" that are difficult to tell apart. These ones are known coral eaters, I can't think of the namesThe shrimp were over by the hammers side when I saw them. I wonder why they were fine for two months and maybe now going after them. They are well fed also
