Common name: fire coral

General information

Millepora alcicornis, commonly known as Fire Coral or Branching Fire Coral, is a hydrozoan coral that resembles true stony corals in appearance. Despite its common name and appearance, it is more closely related to jellyfish and other hydrozoans than to actual corals. Fire Coral has a distinctive yellow-brown and sometimes greenish coloration, with white tips on its branches. It is known for its potent sting, which can cause a burning sensation in humans, hence the name 'Fire Coral'.

Care

Fire Coral is a popular choice for reef aquariums due to its unique appearance and growth patterns. It requires moderate to high lighting and strong water flow to thrive. It is important to handle this coral with care due to its stinging cells. Fire Coral is relatively hardy and can be a good choice for intermediate to advanced aquarists. It benefits from the addition of calcium, strontium, and other trace elements to the water.

Symbiosis

While Fire Coral does not have the same type of symbiotic relationships as some other corals, it can serve as a substrate for other marine organisms. Small crustaceans and fish may seek refuge among its branches, and it can occasionally be found growing on or near other coral species.

Habitat

Millepora alcicornis is found in shallow tropical and subtropical waters of the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. It typically grows on reef slopes and is often found in areas with strong wave action, which helps to deliver nutrients and remove waste products. Fire Coral can form extensive colonies and is an important contributor to reef structure and biodiversity.
