hey all, went round my friend from works house the other day to see his marine tank it looked lovely, but as i only keep tropical at the moment (eventually want to get a reef tank one day!) i seemed to think he had alot of shrimp in there and was wondering if it was ok? i know his tank is 215L , in it he has 1 blue tang , 1 peppermint shrimp , 1 cleaner shrimp, 1 blood shrimp , 1 camel shrimp, 5 hemit crabs, his tank looks really nice and his tang seems to be happy but as i say i'd thought i'd see what some of you guys think oh yeah forgot he had a boxing shrimp in there too
