Orange Sun Coral
Tubastrea faulkneri

The Orange Sun Coral is grouped into the Large Polyp Stony corals (LPS) under the Family: Dendrophyliidae, Genus: Tubastrea, Species: faulkneri. The name Tubastrea, comes from the Latin words for tube (tubus) and star (astron), and this describes its skeletal structure, which is tubular, with stars at the tip of each tube. Tubastreae are commonly known as the Sunflower Corals.

The common name of Orange "Sun" Coral is misleading, since this is a coral that grows in areas of low to no lighting.. Also, this coral lacks zooxanthellae, the microorganisms, which turns sunlight into food for corals. Tubastrea are found upside down at the entrance of caves because their waters supply a very rich diet of plankton and nutrients.

Due to the lack of zooxanthellae, this coral feds by catching prey during low light conditions (dusk until dawn). When the coral is hungry or senses food, it will extend its' feeding tenticles to catch small crustaceans and fish larvae, mysis and small shrimp.

Generally, Ocellaris clownfish are hardier, and slightly less aggressive than its Percula counterpart.
