Aussie Ultra Button Scoly

About this coral

Aussie Ultra Button Scoly is a collector-style “button” LPS coral (often sold in the Scoly/Scolymia/Homophyllia group) chosen for its single, disc-like polyp presence and showpiece look in reef aquariums. In practice, it’s a sand-bed, low-light coral that you spot-feed to support health and full inflation, making it a standout centerpiece for aquarists who prefer low-flow feeding corals over fast, high-turbulence placements.

Features:

• Solitary, disc-shaped polyp design that inflates over its skeleton for a centerpiece “button” look.
• Best kept in low-light, gentle flow conditions, since strong light/current are common stressors for this coral group.
• Sand-bed or low-rock placement in a shaded area helps it expand and maintain normal feeding posture.
• Target/spot feeding with meaty foods supports growth and overall condition beyond relying on light alone.
• Needs clear space from neighboring corals because sweeper-tentacle behavior can increase the chance of stinging nearby tankmates.
• Typically suited to calm reef setups where you can manage flow and prevent irritation from overgrowth or aggressive neighbors.

• Adult size (typical range): About 3–4 inches in diameter (for a healthy specimen)
• Diet: Target feed meaty foods such as mysis shrimp and other small seafood a few times per week
• Water temperature: 73–84°F
• pH: 8.1–8.4
• Salinity: Specific gravity ~1.025
• Alkalinity (dKH): 8–12 dKH
