Net Coral

About

Net Coral (Alveopora catalai) is a branching stony coral from the Western Central Pacific, where it forms impressively large stands on soft substrates in deeper or sheltered, turbid water. Environments notably different from the high-energy reef zones many corals call home. In the wild, colonies can spread well beyond what any home aquarium could contain, built from irregularly forking branches whose corallites form a lattice-like mesh of interlocking rods and spines. The structural feature that inspired the common name. The polyps themselves are large and showy, with swollen tentacle tips that give an almost bubble-like appearance when fully extended. Coloration runs from pale tan when retracted to warm amber or yellow when open, with white oral discs and occasionally white-tipped tentacles creating a pleasant two-tone contrast. In the aquarium this species demands serious commitment: it requires intense lighting and brisk water movement to thrive, and its sensitivity to water quality and flow dynamics puts it firmly in advanced territory. Hobbyists who have kept other Alveopora species will find catalai broadly similar in its needs but even less forgiving of lapses. It is reef safe and poses no threat to neighboring corals, but it needs careful placement and consistent, experienced husbandry to do well long-term.
