Gold Tip Torch
Frogspawn Coral Care
Torch corals are some of the most popular stony corals in the reef aquarium hobby. Torch corals have long tentacles tipped with a ball. This large polyp stony coral (LPS) is one of the most popular stony corals with reef keepers because of the way it sways in the current. Torch corals are similar in growth and care requirements to its Euphyllia cousins, the Hammer coral and the Frogspawn coral. Please see below for additional care tips for Torches as well as checking out our Top 5 Tips for setting up a reef.
Euphyllia corals are found all over the tropical waters of the Pacific. In particular, they are regularly harvested from the islands of the Indo-Pacific including Fiji, Tonga, Solomon Islands, and the Great Barrier Reef. This variety is from Indonesia.
Euphyllia corals such as Hammers, Torches, and Frogspawn do not require as much light as some other corals. They can be kept under normal output fluorescents without much difficulty. In some cases, Torches may extend more readily under subdued lighting, however it may display more attractive colors when placed under stronger lighting.Low Light
Low light translates to about 30-50 PAR
Medium Light is between 50-150 PAR
High Light is anything over 150 PAR
Lighting is a loaded topic, so for a more in-depth discussion of lighting, please see our Deep Dive article.
Moderate to strong water movement is recommended. One of the main draws to this type of LPS coral is how it sways in the current. Water flow is both healthy for the coral and is pleasing aesthetically.
Like most coral, Euphyllia rely to a large extent on the products of their zooxanthellae, however, in our experience, they also benefit from direct feeding. Hammers, torches, and frogspawn do not seem to aggressively feed like other LPS, so finding the right food can be a challenge. We have had some good luck with a dry pellet food called Sustainable Aquatics Hatchery Diet. It is intended for use with small fish, but we have tried feeding it to corals like the Euphyllias, which tend to be finicky eaters, with good results.
A Word of Warning
Euphyllia are one of the corals that extends long sweeper tentacles. Sweeper tentacles are often used as a means of defense against other encroaching coral colonies. Their white tips contain a concentration of nematcysts that can damage more delicate tank mates. Most of the time, this is not a major problem but to be safe, we recommend placing it in a location far from other corals initially.
This genus for the most part has been propagated extensively in captivity and is an excellent candidate for aquaculture. They are not particularly fast growing so long-term aquaculture may be a challenge. It is reasonable to believe that a sustainable harvest can be achieved in time.
Proper acclimation is extremely important considering the stress imposed on the animals by the shipping process. Please take a moment to review our Acclimation Guide.
