Chinese Lettuce Coral

About

Chinese Lettuce Coral (Mycedium robokaki) is a plating coral that grows in flat, thin sheets rarely more than a few millimeters thick, giving colonies a delicate, leafy appearance that earns the common name. The edges of each plate tend to be smooth rather than ruffled, and the overall form is unifacial, meaning corallites appear only on one side of the lamina. Those corallites are small and noticeably tilted across the plate surface, sometimes arranged in loose concentric patterns that give the colony a subtle, almost architectural geometry. Coloration runs toward warm tans and soft pinks, with paler, almost washed-out margins along the plate edges. In the wild, this species occupies sheltered reef zones where wave energy is low, and that preference translates directly to the aquarium: it does best with gentle, consistent flow rather than turbulent or direct blasts. Lighting needs are moderate, so it can be placed at mid-level in most reef tanks without much fuss. Care is rated intermediate, mainly because plating corals in general are sensitive to physical damage and sedimentation, and their thin growth form means poor placement can cause shadowing and tissue recession. If you give it a stable, calm environment, it tends to be a rewarding and visually interesting addition to a mixed reef.
