Around the World Reef and Coral Fish

For more than 240 million years Living Corals have existed on reefs around the world. Related to Sea Anemone and Jelly Fish, Living Corals are difficult to keep, as they require very good water quality.
In order to maintain the appropriate level of water quality, the National Aquarium uses filtration systems involving UV sterlisation and protein skimming. And, behind the scenes there is a mini propagation area where coral cuttings are grown as replacements, helping avoid the difficult process of sourcing new corals. Some soft corals wander about the reef therefore, at the National Aquarium, the Living Coral collection changes regularly.
Names: Sea Anemone.
Habitats: Coral reefs of the Indo-Pacific.
Size: 5-15cm in length.
Special Features: Brightly coloured and deadly to many small fish.
Famously featured in the blockbuster kids film 'Finding Nemo', Sea Anemones are predatory ocean life forms named after the anemone, a terrestrial flower. Sea Anemones are closely related to corals, jellyfish and tube-dwelling anemones.
Many Sea Anemones form symbiotic relationships with single-celled algae that live within their cells. With stinging cells in their tentacles to stun their food, most fish are considered potential food for the Sea Anemone. Anemone fish exude mucus, which protects them from the poisonous stings of the Sea Anemone, and receive protection from predators while within the tentacles of their host. In return the Sea Anemone benefits by sharing some of the food brought to it by the fish.
