Torch corals are relatively hardy and can thrive in a range of lighting and water flow conditions. However, it’s important to strike a balance between providing enough light and flow while avoiding conditions that can harm the coral. In this guide, we will cover everything you need to know about torch coral care, including the best lighting and water flow, how to feed your coral, and common threats to its health.

Torch Coral Characteristics

Torch corals are a beautiful addition to any aquarium, especially if you want to add personality and colour to your underwater landscape. They’re a great choice for both novice and expert marine enthusiasts alike for their vibrant hues and unique appearance.

In this torch coral care guide & information overview, we’ll dive into the characteristics that make torch corals such a popular choice for reef keepers.

Appearance And Color Variations

The torch coral, scientifically known as euphyllia glabrescens, belongs to the family of corals called caulastrea. Its appearance can range from a branching formation, where similar to that of acropora, and a fleshy, bubbly surface that is distinguishable from other corals.

Some torch corals have very long branches, which can reach up to 12 inches in length, while others may have shorter accessories.

Torch corals can be found in several distinct colours ranging from green and brown, which are the most common, to rarer tones like blue, yellow, pink, and purple. These corals can either be single coloured or have different colouration on their tentacle tips and mouths.

Most torch corals contain fluorescent pigments that absorb blue light and emit brilliant colours. This unique feature results in the coral appearing brighter and more vibrant under a blue led light source, which is perfect for illuminating the colours of your torch coral in your reef tank.

Torch Coral Anatomy

The torch coral’s anatomy varies from other coral species. The tentacles, which are located on the top of its branch, contain calcareous skeletons, and the tips of the tentacles are smooth and rounded. Torch coral polyps come in two distinct forms.

One has a tube-like structure that is called the sweeper tentacle; it throws out the mucus coated tentacles and stings any other nearby corals. The other form is a longer tentacle that’s used to capture its prey.

A torch coral’s anatomy also contains a mouth and feeding tentacles that it uses to catch small plankton or shrimp-like creatures. The polyps, where the feeding and defensive tentacles exist, can be retracted into the coral’s skeleton at times of stress.

Torch corals are capable of moving their feeding apparatus to trap food particles as they drift by, thus assisting in maintaining their health.

Growth And Reproduction

Torch corals are a relatively hardy species of coral and can adapt to various lighting and water flow conditions. Depending on their environments, they can grow moderately fast. These corals multiply through sexual reproduction, which involves the spawning of egg and sperm into the water column, where fertilization takes place.

They can also reproduce asexually through budding at the base of their skeleton or by splitting their branches.

Torch corals are not just a treat to watch, but they also have fascinating characteristics that make them a unique addition to any reef tank. By following the right care instructions, you’ll surely find it easy to maintain their health.
