Disc Coral

About

Disc coral (Turbinaria irregularis) is one of the less flashy members of the Turbinaria genus, but it makes up for modest coloration with an interesting growth form that rewards a closer look. Colonies develop as encrusting plates with free, irregular margins that give each specimen a slightly unpredictable outline. No two pieces look quite alike. The corallites themselves are raised and somewhat irregular in arrangement, set against a smooth, even coenosteum tissue between them. Coloration runs from uniform to mottled dark brown, which won't win any beauty contests against more colorful reef inhabitants, but suits a natural, understated aquascape well. In the wild, this species occupies reefs and rocky foreshores across a broad stretch of the Western Central Pacific, found anywhere from the surface down to around 30 meters. That tolerance for lower light levels is one of its more practical traits in a reef tank, making it a reasonable candidate for mid-to-lower placement in the aquarium where other corals might struggle. Care sits at an intermediate level. Not something you'd hand to a complete beginner, but experienced reef-keepers who can maintain stable water quality and moderate flow should find it a manageable and genuinely interesting addition.
