The Great Barrier Reef is Australia's greatest natural treasure, and the world’s largest coral reef. This underwater wonderland stretches for 2,300 km (1,426 miles) from Bundaberg to Australia's northernmost tip. At its closest, it's only 30 km (18.5 miles) away from the Queensland coast.

All corals have four basic needs required to survive -- water quality, food, light, and water movement. In general, hard or SPS/LPS corals are not as flexible as their soft coral cousins, making Mushrooms, Zoanthids, Polyps and Leather Corals some of the favorites for both novice and experienced reefkeepers alike.
