Pore Coral

About

Pore coral (Montipora friabilis) is one of the more architecturally interesting members of a very large genus, building thin, brittle sheets that curl and fold into loose whorls or irregular, almost sculptural contortions. The fronds are unifacial and quite fragile, hence the species name, so even careful handling can cause breakage. Surface texture is noticeably coarse and finely roughened rather than smooth, giving fronds a matte appearance. Corallites are immersed flush into the coenosteum but remain clearly visible to the naked eye, and there are no raised papillae between them. Coloration is understated: typically a pale brown or soft mauve that suits a natural reef aesthetic, though color can shift depending on lighting and water chemistry. In the wild this species turns up in shallow lagoons and turbid inshore reef zones across a broad sweep of the Indo-West Pacific. Polyps can extend during daylight hours, which adds a bit of life to the colony when conditions are right. In the aquarium this one sits firmly in the advanced category. It demands intense lighting and strong, consistent water movement, and its physical fragility means placement and flow direction both need careful thought. Not a coral to start with, but rewarding for reefers who can meet its demands.
