Remember the part in the movie Finding Nemo when the gramma freaked out when Nemo told them that he was from the ocean? Then the cleaner shrimp cleaned Nemo and all was well? If only disinfecting fish were that simple in real life! Though cleaner shrimps do help with cleaning their fellow aquarium inhabitants, they are not miracle workers. That is where we as aquarists come in. We must quarantine and medicate new arrivals to ensure their health and the health of the overall fish community they will be living with.
