Branched Finger Coral

About

Branched finger coral (Porites furcata) is a stony coral native to the shallow and mid-slope reefs of the Western Central Atlantic, where it forms compact clusters of cylindrical branches with distinctly flattened tips. The corallites are deeply set into the branch surface, giving the colony a somewhat pitted or cratered texture up close. Coloration runs a consistent grey-brown, so this isn't a coral you'd choose for bold color contrast, but the growth form itself is tidy and architectural in a reef display. One of the more interesting behavioral traits is that the polyps frequently extend their tentacles during daylight hours, which is less common among stony corals and makes colonies look more lively during the day than many of their relatives. In the wild, these corals are found anywhere from the surface down to around 50 meters, suggesting reasonable adaptability to varying light conditions, though high output lighting is the right approach in captivity. Moderate water movement suits this coral well. As a Porites, it shares the genus's general reputation for being hardier than many other small polyp stony corals, but it still demands the stable water quality and careful husbandry that come with intermediate-level reef keeping. It's reef safe and poses no threat to neighbors.
