General information

The Lizard Island Favia, scientifically known as Favia lizardensis, is a species of stony coral that is popular among reef aquarium enthusiasts. This coral is known for its robustness and the beautiful, often vibrant colors it can display, ranging from greens and browns to more intense reds and purples. Each polyp is surrounded by a hard, calcium carbonate skeleton which contributes to the structure of coral reefs.

Care

Favia corals, including Favia lizardensis, are relatively hardy and can be a good choice for both beginner and intermediate reef keepers. They require moderate lighting and water flow to thrive. It's important to provide them with stable water conditions and maintain calcium, alkalinity, and magnesium levels to support their skeletal growth. They can benefit from supplemental feedings of microplankton or other coral foods.

Symbiosis

While Favia lizardensis does not have the same type of symbiotic relationships as clownfish and anemones, it does host zooxanthellae, symbiotic algae, within its tissues. These algae provide the coral with essential nutrients through photosynthesis, which is why adequate lighting is crucial for the coral's health.

Habitat

The natural habitat of Favia lizardensis is the coral reefs around Lizard Island in the Great Barrier Reef, Australia. They are typically found at various depths, often in areas with moderate water movement which helps in the delivery of nutrients and removal of waste products.
