Ribbon Coral

About

Ribbon coral (Agaricia tenuifolia) is a Caribbean species found across shallow reef environments from the surface down to about 15 meters, ranging broadly through the Caribbean Sea. In the wild it grows as a cluster of thin, upright fronds that stand bifacially. Meaning corallites appear on both faces of each blade. The fronds tend to be elongated and irregularly branched, with thin, sometimes wavy margins that give the colony a somewhat ruffled, lettuce-like appearance. Coloration runs from brown to greenish or rusty tones, occasionally showing pale edges where the septo-costae catch the light, and some specimens display orange tentacles when extended. The corallites themselves sit in short concentric valleys rather than the branching ridges you see in some other Agaricia species, which helps distinguish it once you know what to look for. In the aquarium this is a relatively forgiving choice, tolerating lower light and gentle water movement better than many reef corals. Conditions that make it accessible to hobbyists who are still getting comfortable with coral husbandry. It works well in lower-energy areas of a reef tank where more demanding SPS corals would struggle. Just give it stable water quality and room for its fronds to develop without being shaded out by faster-growing neighbors.
