Pore Coral

About

Pore coral (Montipora circumvallata) is a Western Indian Ocean species found on shallow reefs from just a couple of meters down to around twenty meters depth. What sets it apart visually from many other Montipora is its complex surface architecture. The colony grows as a partly encrusting base with irregular upward projections, and the entire surface is covered in elongated bumps that tilt along the colony and fuse into distinct ridges at the tips of those upgrowths. The individual corallites are nestled between these ridges in tidy vertical rows, giving the coral a uniquely sculpted, almost topographic appearance. Coloration tends toward greenish-grey with contrasting polyp tones, which can shift depending on lighting and water chemistry. In the aquarium, this species demands conditions that closely mirror its natural reef habitat. Very high light intensity and strong, consistent water movement are non-negotiable. Like most Montipora, it is photosynthetic and relies heavily on zooxanthellae, but keeping the tissue healthy at this level of light and flow takes genuine experience. This one is best suited to a well-established reef tank managed by a keeper who already has a handle on nutrient export, alkalinity stability, and flow dynamics. Not a beginner coral.
