Small Crack is a small break in the Sha’ab Mahmud reef system and is navigable by small dive boats only. The passage is 6m deep and 2-3m across with reef walls on both sides. Both hard and soft corals abound here – you can see Gorgonian fans, porites, salad coral and Acropora as well as anemones and their omni-present anemonefish. There is also a small eel garden at a depth of 19m and many species of reef fauna. Pelagic fish also frequent the site.
