Clean-up crews are like having janitors for your tank; they pick up waste and take it out for you and help keep your tank as clean as possible. It's important to have these guys in your tank because they play a major role in helping you do less work as far as cleaning the tank goes. They will feed on algae, leftover food, and detritus from your tank, leaving it more pristine for your fish or corals to live in.
