A couple of months ago I bought about 10 shrimp. They were just called algae eating shrimp at the LFS, but I think they are amanos. One of them has grown to a huge size, while the rest have stayed at about an inch. This guy is closing in on 3 inches. I am hoping he is strictly a vegetarian since there are some pretty small fish in that tank. Has anyone ever heard of an amano growing to that size, or could this be some other type that got mixed in? Originally he had the same markings as all the others, and still looks similar, but much much larger.
