A clean up crew is an essential part of any reef aquarium. They are invertebrates they help to naturally control and manage nuisance algae and detritus. Here you can find the invertebrates and clean up crew we carry and ship across Canada. We sell turbo snails, emerald crabs, hermit crabs and many different kinds of snails. We also sell different reef shrimp like peppermint shrimp, cleaner shrimp, blood shrimp and harlequin shrimp.
