Hollygray A (one Head) Torch coral

Euphyllia glabrescens, commonly known as the torch coral, is a stunning species of large-polyped stony coral that belongs to the family Euphylliidae. This coral is characterized by its long, sweeping tentacles that can reach impressive lengths and are adorned with potent cnidocytes, giving it a distinctive appearance reminiscent of a flaming torch. Typically found in shallow reef environments, torch coral thrives in vibrant, warm waters, making it a popular choice among marine aquarium enthusiasts, particularly for those looking to create a striking underwater landscape.

In terms of appearance, the Hollygray A Torch coral exhibits a beautiful array of colors, often showcasing hues of green, blue, and purple. The tentacles are a standout feature, swaying gracefully in the water, which not only adds to its aesthetic appeal but also serves a functional purpose in capturing food particles from the water. This species is known for its relatively fast growth rate and ability to form large colonies, making it a favorite among aquarists looking for dynamic coral displays in their tanks.

Behaviorally, Euphyllia glabrescens is generally peaceful and can coexist with a variety of other coral species. However, it is essential to monitor its interactions with more aggressive corals, as the long tentacles can potentially compete for space and resources. In its natural habitat, torch coral often forms symbiotic relationships with various marine organisms, enhancing both its survival and the biodiversity of the reef.

Hollygray A Torch coral is primarily found in the Coral Triangle region, particularly around Indonesia and Fiji, where it plays a crucial role in the reef ecosystem. Its ability to adapt to different environmental conditions makes it a resilient species, capable of thriving in a range of marine settings. This adaptability, combined with its striking appearance, has made it a staple in the marine aquarium trade.

When caring for Hollygray A Torch coral, maintaining optimal water parameters is crucial for its health and growth. Ideally, the water temperature should be kept between 24°C and 28°C, with a salinity range of 1.023 to 1.025 ppt. The pH level should be maintained between 8.1 and 8.4 to support the coral's metabolic functions. A minimum tank size of 100 liters is recommended to provide ample space for growth and movement.

Feeding torch coral involves providing a balanced diet of zooplankton and other small particulate foods, as they are primarily photosynthetic but benefit from additional nutrients. Regular feeding every few days can promote healthy growth. It's also essential to ensure that the coral has access to adequate light, as this species thrives in well-lit environments, preferably under LED or metal halide lighting.

In terms of compatibility, Hollygray A Torch coral can coexist with various peaceful fish and invertebrates, but caution should be taken around more aggressive species that may harm its tentacles. Acclimation should be gradual to prevent shock; floating the coral in the tank for about 20-30 minutes before introducing it to the aquarium is recommended. Quarantine new specimens for at least two weeks to monitor for any signs of disease or pests before adding them to the main display tank.

Hollygray A Torch coral is suitable for shipping, provided it is packed securely to minimize movement and stress during transit. A packing density of 1 to 2 pieces per 100 liters of shipping water is advisable to ensure adequate space and oxygen levels. Temperature sensitivity is a factor to consider, so maintaining a stable shipping temperature between 24°C and 28°C is essential during transport. This species is not listed under CITES, but responsible sourcing practices from Bali, Indonesia, ensure sustainable export.
