This abundance of creatures that are dependent on a specific structure has given coral the nickname the rainforest of the seas. Reef tanks are an attempt to recreate a wild coral reef and providing all the things that corals need to thrive. Reefs begin when a polyp attaches itself to a rock on the sea floor then divides. And the variety of species living on coral reefs is greater than almost anywhere else in the world.

2014 unfortunately reefs worldwide are threatened by an increasing array of impacts primarily from global climate change unsustainable fishing practices and land based. C overing less than one percent of the ocean floor coral reefs support an estimated 25 percent of all known marine species. Offering vibrant colors and the greatest biodiversity of any marine ecosystem on the planet. At the ocean floor we have everything that is needed to create the reef tank of your dreams.

2012 costanza et al. Despite covering less than 1 percent of the ocean floor coral reefs are home to 25 percent of all fish species. Coral reefs only take up about 1 of the ocean floor but host an estimated 25 of all ocean species. The national park service has ten parks with coral reefs.

Some coral reefs are so large they are even visible from outer space. A coral reef is an underwater ecosystem characterized by reef building corals reefs are formed of colonies of coral polyps held together by calcium carbonate most coral reefs are built from stony corals whose polyps cluster in groups. Coral reefs are amazing habitats. Coral belongs to the class anthozoa in the animal phylum cnidaria which includes sea anemones and jellyfish unlike sea anemones corals secrete hard carbonate.

Fish harvested from coral reefs feed tens of millions of people in developing countries and reef related fishing trade and tourism generates up to 30 billion annually accounting for more than 15 percent of the gdp of 23 nations. But coral reefs only occupy less than one tenth of one percent of the ocean floor. Corals in captivity are mostly housed in reef tanks. They provide significant ecological economic and societal benefits valued globally at about usd 9 8 trillion each year de groot et al.
