Common name: Torch coral

General information

The Torch Coral, scientifically known as Euphyllia glabrescens, is a large polyp stony (LPS) coral that is highly sought after in the reefkeeping hobby. Its long, flowing tentacles and bright, fluorescent colors make it a visually striking addition to any reef aquarium. The Torch Coral can come in a variety of colors, including green, brown, yellow, and sometimes with tips of a different color, which can fluoresce under actinic lighting.

Care

Torch Corals require moderate to high lighting and moderate water flow to thrive in a reef aquarium. They are relatively hardy but should be placed in an area of the tank where they will not be damaged by other corals or strong currents. It's important to provide them with plenty of space as they can be aggressive towards other corals with their long sweeper tentacles. Feeding is not strictly necessary as they receive most of their nutrients from photosynthesis, but they can benefit from occasional feedings of small meaty foods.

Symbiosis

While Torch Corals do not have as many symbiotic relationships as some other marine species, they can host a variety of small marine organisms, including certain species of clownfish, which may seek refuge among their tentacles, similar to anemonefish with sea anemones. However, this is less common and not all clownfish species will associate with Torch Corals.

Habitat

In the wild, Euphyllia glabrescens is typically found in the Indo-Pacific region, including the Great Barrier Reef, Fiji, and Tonga. They inhabit reef slopes and lagoons, often in areas with moderate currents which help to deliver planktonic food to the coral and remove waste products.
