"Tank Janitors" are the critters (fish and invertebrates) that crawl and/or swim around your tank, cleaning up the crud (detritus, uneaten food, undesirable microalgae, etc.) that builds up in a saltwater aquarium, disrupting the biological balance and appearance. "Reef Tank Safe Janitors" do it without destroying your corals and other tank mates.
