Frogspawn Coral Care Guide
Euphyllia divisa · Saltwater LPS Coral
What Frogspawn Coral look like
Euphyllia divisa, commonly known as Frogspawn Coral, exhibits a distinctive morphology characterized by its elongated, fleshy polyps that can reach up to 10 inches in length. The coral features bulbous tips that resemble frogspawn, hence its common name. The coloration varies widely, ranging from green to pink and purple, often with contrasting hues on the tips. This species displays a robust skeleton composed of aragonite, with a well-defined corallite structure that houses the polyps. Sexual dimorphism is not pronounced in this species, but individual polyps may exhibit slight variations in size and coloration. Defensive adaptations include the presence of nematocysts within the tentacles, which can deliver a mild sting to deter potential predators. The coral's polyp extension can be quite pronounced, particularly during feeding or at night, enhancing its ability to capture planktonic food.
Behavior & temperament
Euphyllia divisa is primarily a sessile organism that exhibits a degree of movement through the extension and retraction of its polyps. It is known to engage in aggressive behaviors towards neighboring corals, utilizing its stinging tentacles to defend its territory. This coral is typically found in colonies, where individual polyps can exhibit a social hierarchy based on size and health. During the night, the polyps extend significantly to feed on zooplankton and phytoplankton, showcasing a feeding behavior that is both opportunistic and reliant on the surrounding water column. Frogspawn Coral can also engage in symbiotic relationships with zooxanthellae, providing it with additional energy through photosynthesis, although it primarily relies on heterotrophic feeding.
Diet & feeding
Euphyllia divisa is primarily a carnivorous coral that feeds on zooplankton and phytoplankton in its natural habitat. In captivity, it requires a diet supplemented with small meaty foods, such as brine shrimp and specialized coral foods, to thrive.
Behind the name
The genus name 'Euphyllia' is derived from the Greek words 'eu' meaning 'well' and 'phyllon' meaning 'leaf', referring to the leaf-like appearance of its polyps. The species name 'divisa' comes from the Latin word for 'divided', which may refer to the distinct separation between the polyps.
