Google flatworms or planaria. They are a small flat blob-like creature that can multiply into an epidemic & cover your sand, corals, glass very quickly. The red ones I think are the worse & they can kill off your corals when their numbers are too high. Any coral or frag from a flatworm infested tank needs to be freshwater dipped to knock off any flatworms. Flatworm Exit is the normal chemical treatment for killing these pests.
