Aquarium Requirements

Holy Grail Torch Coral is a beautiful coral that can be a great addition to your reef aquarium. However, to keep it healthy and thriving, you need to provide it with the right environment.

Here are the aquarium requirements for Holy Grail Torch Coral:

Water Parameters

Holy Grail Torch Coral requires typical reef aquarium water parameters, including a temperature around 75°F – 80°F (24°C – 27°C), a specific gravity of about 1.023 – 1.025, a pH of about 8.1 – 8.4, and a calcium level of around 420 – 440 ppm. It is also important to keep the nitrate and phosphate levels low, as high levels of these can harm the coral.


Holy Grail Torch Coral requires moderate to high lighting. LED lights are a good choice for this coral, as they can provide the right spectrum and intensity of light. The recommended PAR level for Holy Grail Torch Coral is between 150 – 250.

Water Flow

Like most large polyp stony (LPS) corals, Holy Grail Torch Coral benefits from moderate water flow. This can help to deliver nutrients and oxygen to the coral, as well as remove waste products. However, excessive water flow can damage the coral, so it is important to strike a balance.


Holy Grail Torch Coral is a photosynthetic coral, which means that it gets most of its energy from the light. However, it also requires supplemental feeding. You can feed it with small pieces of meaty foods, such as brine shrimp, mysis shrimp, and krill. It is important not to overfeed the coral, as this can lead to poor water quality and harm the coral.

Feeding and Nutrition

Feeding and Nutrition

Holy Grail Torch Euphyllia is a photosynthetic coral, which means that it can produce its food through photosynthesis. However, it still requires supplemental feeding to ensure its optimal growth and health.

The coral feeds on a variety of small organisms, including plankton, brine shrimp, and mysis shrimp. It is essential to provide a well-balanced diet that includes all the necessary nutrients. Feeding the coral two to three times a week is recommended, but it is essential not to overfeed the coral as it can lead to poor water quality.

When feeding the coral, it is best to turn off the pumps to reduce the flow. This allows the coral to catch the food with its long tentacles. It is also recommended to target feed the coral by using a pipette or turkey baster to deliver the food directly to the coral’s mouth.

In addition to feeding, it is also crucial to maintain proper water quality. The coral requires stable water parameters, including temperature, salinity, and pH, to grow and thrive. It is recommended to perform regular water changes and test the water regularly to ensure it is within the appropriate range.

Propagation of Holy Grail Torch Coral

Propagation of Holy Grail Torch Coral is a popular practice in the aquarium hobby. Fragging and propagating the coral is a way to create new colonies and share the beauty of this coral with others.

To propagate Holy Grail Torch Coral, the first step is to prepare the coral for fragging. This involves removing the coral from the aquarium and placing it in a container of aquarium water. The coral should be allowed to acclimate to the new environment for at least 30 minutes before fragging.

Once the coral is ready, the next step is to frag it. The coral can be fragged using a bone cutter or a frag saw. It is important to make clean cuts to avoid damaging the coral. The cut should be made at the base of the coral, leaving a small amount of tissue on the mother colony.

After fragging, the coral should be dipped in a coral dip to remove any pests or parasites. The coral should be allowed to dry before being glued onto a frag plug or a piece of live rock. The frag should be placed in an area with moderate to high flow and moderate lighting.

Propagation of Holy Grail Torch Coral requires patience and attention to detail. It is important to monitor the frag for signs of stress or disease. With proper care, the Holy Grail Torch Coral can grow into a beautiful and healthy colony.

Common Issues and Solutions
Common Issues and Solutions

Issue: Receding or Discolored Tissue

If you notice the tissue on your Holy Grail Torch is receding or changing color, it may be a sign of stress. This can be caused by a number of factors, including improper water parameters, inadequate lighting, or pests.

Solution: Check Water Parameters and Lighting

Test your water parameters and make sure they are within the optimal range for the Holy Grail Torch. This includes maintaining a calcium level between 420-440 ppm and an alkalinity level between 8-11 dKH. Ensure that your lighting is strong enough to support the coral’s needs. If you suspect pests, inspect the coral closely and take appropriate action.

Issue: Bleaching

Bleaching occurs when the coral expels its zooxanthellae, causing it to turn white. This can be caused by sudden changes in water temperature or lighting.

Solution: Adjust Lighting and Temperature

If you suspect bleaching, adjust the lighting and temperature of your tank. Gradually acclimate the coral to any changes to prevent further stress.

Issue: Algae Overgrowth

Algae overgrowth can smother the Holy Grail Torch and prevent it from receiving adequate light and nutrients.

Solution: Control Algae Growth

Control algae growth by reducing nutrient levels in the water, increasing water flow, and performing regular water changes. You can also manually remove algae from the coral using a soft-bristled brush or tweezers.

By addressing these common issues and implementing the appropriate solutions, you can help ensure the health and longevity of your Holy Grail Torch coral.
