Serpent Coral

About

Serpent coral (Pachyseris rugosa) is one of those corals that looks like it was carved rather than grown, its surface etched with ridge-like walls that give it a distinctly textured, almost topographic appearance. In the wild across the Indo-Pacific, colonies can spread well beyond a metre across, forming large mound-like structures in shallow water or flatter, irregular plates at greater depths down to around 40 metres. It turns up across a broad range of reef environments, including spots exposed to fairly strong wave surge, which speaks to its resilience. Coloration tends toward deep brown or a muted bluish-grey. Nothing flashy, but the sculptural form more than compensates. The bifacial, contorted plate growth habit means no two colonies look quite alike, and a mature specimen has a presence that more colorful corals can't replicate. In the aquarium, this is a solid choice for a keeper with some experience under their belt. It asks for moderate light and flow and doesn't demand the exacting conditions that more sensitive corals require, but like most large-polyp plating corals it benefits from stable water quality and room to expand without crowding neighbors. A patient, thoughtful approach will be rewarded with a genuinely architectural centerpiece.
