Scroll Coral

About

Scroll coral (Agaricia undata) is a Western Atlantic species found across the Caribbean Sea and along the eastern Brazilian shelf, growing on shallow reefs from just below the surface down to considerable depth. In the wild it tends to inhabit lower-light reef zones, which makes it a relatively practical choice for reef hobbyists who can't run high-intensity lighting. The colony structure is what sets it apart visually. It grows as flat to upright plates arranged in that characteristic scrolling, layered form the common name references. Look closely and you'll see long, roughly concentric valleys running across the surface, widely spaced with flat bottoms and small corallites packed tightly along the valley walls. Coloration runs toward dark yellows, greens, and browns rather than anything flashy, so this isn't a coral people typically buy for bold color. It does, however, bring genuine textural interest to a tank. Care requirements lean toward the forgiving end of the spectrum. Low light and low flow suit it well, and its beginner rating reflects that it doesn't demand the precision that many reef corals do. It is reef safe and poses no aggression concerns toward neighbors. For a hobbyist looking to add an interesting growth form without the complexity of more demanding species, scroll coral is worth considering.
