Brain Coral Care Guide
Favia speciosa · Saltwater LPS Coral
What Brain Coral look like
Favia speciosa, commonly known as Brain Coral, exhibits a robust, encrusting morphology characterized by its distinct, convoluted ridges and valleys that resemble a brain's surface. This species can reach a maximum diameter of approximately 12 inches (30 cm) in adult specimens. Sexual dimorphism is not pronounced in Favia speciosa, as both sexes exhibit similar physical characteristics. The coral possesses a hard, calcareous skeleton that provides structural integrity, while its polyps, which are typically extended at night, exhibit a unique morphology with a prominent mouth and tentacles that can retract into the corallite structure during the day. Defensive adaptations include the presence of nematocysts within the tentacles, allowing the coral to fend off potential threats and compete for space on the reef. The coloration can vary widely, ranging from green to brown, often with contrasting hues that enhance its visual appeal.
Behavior & temperament
Favia speciosa is a primarily sessile organism, exhibiting limited movement through the extension and retraction of its polyps. It engages in a symbiotic relationship with zooxanthellae, which reside within its tissues, facilitating photosynthesis and providing the coral with essential nutrients. During the day, the polyps remain mostly retracted, but at night, they extend significantly to capture plankton and organic particles from the water column, showcasing a feeding behavior that is both opportunistic and reliant on available food sources. The species does not exhibit aggressive territorial behavior towards other corals, but it can engage in competition for space through overgrowth and shading.
Diet & feeding
Favia speciosa is primarily a heterotrophic feeder, capturing zooplankton and organic detritus from the water column, while also relying on the photosynthetic products of its symbiotic zooxanthellae. In captivity, it requires a diet supplemented with finely chopped meaty foods and high-quality coral pellets to ensure optimal health.
Behind the name
The scientific name 'Favia' is derived from the Latin word 'favus', meaning 'honeycomb', referring to the coral's structure, while 'speciosa' comes from the Latin 'speciosus', meaning 'beautiful' or 'showy'.
