Finger Leather Coral Care Guide
Sinularia flexibilis · Saltwater Soft Coral
What Finger Leather Coral look like
Sinularia flexibilis, commonly known as Finger Leather Coral, exhibits a distinctive morphology characterized by its elongated, finger-like polyps that can reach up to 30 cm in height. The colony typically presents a fleshy, flexible body that is a pale yellow to brown color, often with a smooth surface texture. The polyps are retractable and can extend significantly during feeding or in response to water flow. This species lacks a rigid skeleton, which allows for its characteristic flexibility. There is minimal sexual dimorphism observed in this species, as both male and female polyps share similar physical traits. Defensive adaptations include the production of secondary metabolites that can deter herbivores and potential threats, while the coral's ability to retract its polyps provides additional protection against physical disturbances.
Behavior & temperament
Finger Leather Coral exhibits a relatively passive behavior, primarily relying on its symbiotic relationship with zooxanthellae for energy through photosynthesis. It extends its polyps during the day to maximize light capture and retracts them at night. This species does not exhibit aggressive interactions with other corals but can engage in allelopathic behaviors to inhibit the growth of nearby competitors. Movement is limited, as it is typically anchored to the substrate, but it can sway gently in water currents, enhancing its feeding efficiency. The coral's stinging potential is low, with nematocysts primarily used for capturing planktonic food rather than for defense.
Diet & feeding
Sinularia flexibilis is primarily heterotrophic, feeding on plankton and organic detritus in the water column. In captivity, it thrives on a diet supplemented with finely chopped meaty foods, liquid coral foods, and phytoplankton.
Behind the name
The genus name 'Sinularia' is derived from the Latin word 'sinus', meaning 'bay' or 'fold', referring to the folded appearance of the coral's polyps. The species name 'flexibilis' translates to 'flexible' in Latin, highlighting the coral's characteristic pliability.
