Leptoseris Coral Care Guide
Leptoseris explanata · Saltwater SPS Coral

What Leptoseris Coral look like
Leptoseris explanata exhibits a distinctive morphology characterized by its encrusting growth form, which can reach a maximum diameter of approximately 30 cm. The coral displays a unique structure with thin, flat plates that are often irregularly shaped, creating a rugged surface texture. Its coloration varies from pale yellow to brown, often with a subtle iridescence. The polyps are small and retractable, typically extending only during the night, and possess a simple structure with a limited number of tentacles. This species lacks prominent septa, which contributes to its smooth appearance. Defensive adaptations include the ability to retract polyps quickly and a potential for limited stinging through its nematocysts, although these are not as potent as those found in more aggressive corals.
Behavior & temperament
Leptoseris explanata is primarily a solitary coral species that exhibits a low level of aggression towards neighboring corals, often cohabiting peacefully in reef environments. It is a slow-growing species that relies on both photosynthesis and heterotrophic feeding, extending its polyps to capture plankton and organic particles during the night. Its symbiotic relationship with zooxanthellae allows it to thrive in moderate light conditions, enhancing its growth and resilience. The coral's movement is minimal, as it is firmly attached to substrates, but it can exhibit localized expansion and contraction of its tissue in response to environmental changes.
Diet & feeding
Leptoseris explanata is an obligate photosynthetic coral, relying on symbiotic zooxanthellae for energy, while also capturing planktonic food particles in the water column. In captivity, it requires a diet supplemented with fine particulate foods and occasional phytoplankton to support its nutritional needs.
Behind the name
The genus name 'Leptoseris' is derived from the Greek words 'leptos', meaning 'thin', and 'seris', referring to 'plate', while the species name 'explanata' comes from the Latin word meaning 'flattened' or 'spread out', describing its growth form.
