Common name: Dipsastraea
Dipsastraea, commonly known as Brain Coral, is a genus of stony coral found in tropical ocean waters, particularly around coral reefs in the Indo-Pacific region. These corals are named for their distinctive, grooved surface that resembles the folds of a human brain. The genus Dipsastraea is notable for its massive, dome-shaped colonies that can grow to impressive sizes, making them a striking addition to any reef aquarium.
The polyps of Dipsastraea corals are interconnected and share a common skeletal structure, which contributes to their robust and enduring nature. They are primarily photosynthetic, relying on a symbiotic relationship with zooxanthellae algae, which live within their tissues and provide them with nutrients through photosynthesis. This relationship is crucial for their survival, as it allows them to thrive in nutrient-poor waters.
In the aquarium setting, Dipsastraea corals require stable water conditions, moderate to high lighting, and moderate water flow to mimic their natural habitat. They are considered relatively hardy corals but can be sensitive to sudden changes in water parameters. It's important to maintain calcium and alkalinity levels to support their skeletal growth. While generally peaceful, they can engage in competitive interactions with neighboring corals, so adequate space should be provided to prevent aggression.
Dipsastraea corals are a favorite among hobbyists not only for their unique appearance but also for their resilience and ability to adapt to various aquarium settings. They can serve as a focal point in a reef tank, offering both aesthetic appeal and ecological benefits by contributing to the structural complexity of the aquarium environment.
