Cycloseris spp. (Green)

Cycloseris spp., commonly known as Fungia-type Disc Corals, are solitary, free-living LPS corals known for their round to oval, flattened or slightly domed skeletons and fleshy, expandable polyps. Unlike many reef-building corals, they are not permanently attached to the substrate and typically rest directly on the sandbed or rubble, where they can slowly move over time. Colors can include green, brown, cream, orange, pink, red, and purple, sometimes displaying contrasting mouths, radial markings, or subtle patterns. Their solitary growth form, hardy nature, and attractive coloration make them a popular choice for reef aquariums.

Care in Aquariums:

• Lighting: Low to moderate, with gradual acclimation to stronger light

• Flow: Gentle to moderate, indirect flow; avoid strong, concentrated currents

• Placement: Sandbed or lower rockwork; provide a clear, stable area around the coral

• Feeding: Primarily photosynthetic but benefits from occasional small meaty foods or fine particulate coral foods

• Space: Allow sufficient room for full polyp expansion and natural movement; avoid placing sharp rock directly underneath or against the fleshy tissue

• Handling: Avoid excessive movement or abrasion of the soft tissue, especially when the coral is fully expanded
