Common name: Tombstone coral

General information

Coeloseris mayeri is a solitary, non-reef building coral species known for its unique fluorescence under actinic lighting. This coral is not commonly found in the aquarium trade but is a prized specimen for advanced hobbyists due to its distinct appearance and glowing effect.

Care

Caring for Coeloseris mayeri requires stable water conditions and moderate to high lighting to maintain its fluorescence. It prefers moderate water flow to mimic its natural environment and to keep its surface free of debris. Feeding is not typically necessary as it contains symbiotic algae known as zooxanthellae that provide most of its nutritional needs through photosynthesis.

Symbiosis

Like many corals, Coeloseris mayeri has a symbiotic relationship with zooxanthellae, which are photosynthetic algae living within its tissues. These algae provide the coral with organic compounds produced through photosynthesis, which is a significant source of its nutrition.

Habitat

Coeloseris mayeri is found in the Indo-Pacific region, typically in deeper waters where it can be exposed to strong currents. It is often located on steep reef slopes or in channels where it can receive ample water flow.
