Flowerpot Coral

About

Found on shallow tropical reefs in the Philippines, Goniopora petiolata is a stony coral in the flowerpot group, named for the long, flowing polyps that extend well beyond the skeleton and give the colony an almost anemone-like appearance when fully open. Like all gonioporas, the polyps have 24 tentacles arranged around a central mouth, a detail that helps separate this genus from the similar-looking alveopora corals, which carry only 12. Each polyp sits atop a raised tube, giving the colony a textured, almost sculptural look even when contracted. In the wild it lives as a benthic organism on shallow reef slopes, where it catches zooplankton and relies heavily on its symbiotic zooxanthellae for nutrition. In the aquarium, Goniopora petiolata sits in intermediate territory. Not a beginner coral, but not completely out of reach for a keeper who has a stable, mature system dialed in. Consistent, high-intensity lighting and moderate water movement are the key environmental factors to get right. Goniopora corals as a group have a historical reputation for declining slowly in captivity, so close observation and good water quality discipline matter more here than with many other stony corals.
