Common name: Lettuce Coral

General information

Gardineroseris planulata, commonly known as Lettuce Coral or Leaf Coral, is a species of stony coral that is appreciated for its unique leaf-like appearance. It is a part of the Agariciidae family and is known for its horizontal plates which resemble the leaves of a lettuce, giving it its common name. This coral is often a pale brown or greenish color, which can add a subtle yet attractive aesthetic to a reef aquarium.

Care

Lettuce Coral is a hardy species that can be a good choice for both novice and experienced reefkeepers. It thrives in moderate lighting conditions and requires moderate water flow to prevent sediment accumulation on its delicate plates. It is important to provide ample space for this coral to spread out and grow, as its plating structure can become quite expansive over time. Feeding is not typically necessary as it relies on its symbiotic zooxanthellae for nutrition, but occasional feeding with microplankton can promote growth and health.

Symbiosis

Like many corals, Gardineroseris planulata hosts symbiotic algae known as zooxanthellae within its tissues. These algae provide the coral with essential nutrients through photosynthesis, while the coral provides the algae with a protected environment and access to sunlight.

Habitat

Lettuce Coral is found in the warm waters of the Indo-Pacific region, particularly on reef slopes and lagoons. It prefers depths where it can receive adequate sunlight for its zooxanthellae to perform photosynthesis effectively, typically not deeper than where light penetration is sufficient for this symbiotic relationship to flourish.
