Ultra Grade Scolymia Australis

Scolymia australis, commonly referred to simply as the scoly, is one of the most iconic and sought-after solitary large polyp stony corals in the marine aquarium hobby. Native to southern Australian waters, these single-polyp corals are celebrated for their circular disc structure and vibrant tissue inflation. This particular specimen is an ultra grade piece measuring approximately 7cm across, showing the dense fleshy mantle and distinct concentric patterning typical of premium Australian imports.

During daylight hours, the polyp swells with water to expand its fleshy mantle across the underlying calcium skeleton, creating a broad, smooth, disc-like appearance. At night, or during targeted broadcast feedings, the coral extends a ring of translucent feeding tentacles from its perimeter and central mouth to trap micro-fauna and suspended meaty particles. It grows slowly, maintaining its solitary form rather than budding into a colonial mass, making it an ideal long-term showpiece for established reef systems.

Care requirements are straightforward for an LPS coral, provided water chemistry remains stable. Aim for low to moderate indirect lighting with PAR values between 50 and 100, paired with gentle, intermittent water flow to keep detritus from settling on the disc. Placement on the sandbed or nestled low on the rockwork is ideal to prevent accidental falls and tissue damage. Provide standard reef parameters, keeping calcium between 420 and 440 ppm, alkalinity at 8 to 9 dKH, and magnesium between 1300 and 1350 ppm. Weekly target feedings of finely chopped mysis or dedicated LPS pellets will support sustained tissue health and growth. Ensure adequate spacing of at least five to eight centimetres from nearby aggressive corals, as contact will result in tissue recession. Acclimate gently via drip acclimation and light ramp down over a couple of hours.
