Common name: Button Coral

General information

The Button Coral, Cynarina lacrymalis, is a large polyp stony (LPS) coral that is highly prized in the reefkeeping hobby for its vibrant colors and unique appearance. It is often referred to as Cat's Eye Coral, Doughnut Coral, or Tooth Coral due to its distinctive circular shape and the tooth-like ridges found on its surface.

Care

Cynarina lacrymalis requires moderate to low water flow and moderate lighting to thrive in a reef aquarium. It is a photosynthetic coral that relies on its symbiotic zooxanthellae for nutrition, but it also benefits from supplemental feedings of meaty foods like mysis shrimp and finely chopped seafood. Stable water parameters and careful placement in the aquarium are crucial to avoid damage to its fleshy polyp.

Symbiosis

While Cynarina lacrymalis does not have any specific symbiotic relationships akin to clownfish and anemones, it does host a variety of microfauna in its mucous layer and on its skeleton, which can contribute to the overall biodiversity of the reef aquarium.

Habitat

In the wild, Button Coral is typically found on reef slopes and in lagoons, often partially buried in sand or nestled in rubble. It is distributed across the Indo-Pacific region, from the Red Sea to the western Pacific Ocean.
