The Plate Coral (Fungia sp. or Cycloseris sp.) is a hardy, single-polyp large polyp stony (LPS) coral featuring a flat or slightly dome-shaped disk covered in fine radiating ridges and short, bead-like tentacles. Highly favored for its distinct circular geometry and intense neon coloration under actinic reef lighting, it is a unique free-living coral that makes an excellent, low-maintenance centerpiece choice for beginners and advanced collectors.
Tank Requirements
Lighting: Low to moderate (50–150 PAR); prefers subdued or indirect illumination, as high-intensity lighting will quickly cause its fleshy mantle to retract and bleach.
Water Flow: Low to moderate; requires a gentle, indirect current to keep sand and detritus from settling on its oral disc without blowing its flesh flat against the underlying skeleton.
Temperature: 72°F – 78°F (22°C – 26°C).
Salinity (Specific Gravity): 1.023 – 1.025.
pH Range: 8.1 – 8.4.
Care and Feeding
Placement: Bottom of the aquarium, resting flat on a soft sandbed or fine substrate; it must never be glued or wedged into rocks, as it is a free-living coral that can inflate itself to slowly inflate, crawl, and flip over if buried.
Diet: Photosynthetic via zooxanthellae, but possesses a massive feeding response and grows significantly faster when target-fed weekly with mysis shrimp, brine shrimp, or specialized LPS pellets.
Temperament: Semi-aggressive; it does not produce long sweeper tentacles, but its short tentacles carry a sharp sting, meaning it must be kept spaced several inches away from other bottom-dwelling corals to prevent territorial tissue damage.
