The Ultra Toxic Apple Scolymia Australian Coral (Scolymia australis) is a solitary large-polyp stony coral prized for its vivid apple and red coloration. It features a single fleshy polyp resting upon a circular calcareous base. This vibrant coral serves as a stunning centerpiece in marine aquariums.

Distribution and Habitat

This species originates from the Western Atlantic and Caribbean where it inhabits sheltered reef slopes. It thrives in calm depths protected from intense wave action and heavy illumination.

Physical Description

The solitary coral displays an intense apple-green disc with contrasting red markings. Its fleshy mantle covers radiating skeletal ridges leading to a central mouth. When fully expanded, the fleshy polyp forms a plump circular cushion.

Diet and Feeding

Scolymia australis relies on photosynthetic zooxanthellae for essential nutrition. Supplemental target feedings of mysis shrimp and coral pellets enhance growth and coloration. Feeding once or twice weekly supports overall vitality.

Behavior and Reproduction

This solitary coral remains a single individual and does not form sprawling colonies. At night, it extends short tentacles around the disc perimeter to capture drifting food. It has a peaceful temperament but requires adequate space from stinging neighbors.

Aquarium Care

Provide moderate lighting and low water movement to encourage full polyp expansion. It can be positioned on the sand bed or secured onto lower rockwork. Stable calcium, alkalinity, and magnesium levels are essential for skeletal development.

Conservation Status

Harvesting is regulated by fisheries management authorities to ensure sustainable wild collection. Populations remain stable throughout its native range. Classified as Least Concern by the IUCN Red List.
