Porites

Porites (family Poritidae) is a genus of small-polyp stony corals distributed across tropical reefs of the Indo-Pacific and Caribbean, encompassing encrusting, hemispherical, and branching growth forms. Massive colonies of some species reach several meters in diameter and are among the oldest living organisms on Earth, with some documented specimens centuries old. The surface texture is smooth and dense, with tiny polyps coloring in green, brown, pink, purple, and yellow. Moderate to high lighting (150–300 PAR) and moderate flow are recommended. Parameters (24–27°C, KH 8–10, Ca 400–440 ppm) should be stable, though Porites demonstrates excellent tolerance for environmental variation—one of the hardiest SPS genera available. Boring worms and polychaetes occasionally infest colonies; monitoring is advised. Fragging is feasible but technically demanding due to the fine polyp structure. Established large colonies contribute unrivaled structural gravitas and ecological realism to mature reef aquariums.
