Lesser Star Coral

About

Lesser Star Coral (Coelastrea palauensis) is a reef-building stony coral native to the Indo-West Pacific, found across a broad range stretching from the East African coast out into the central Pacific. In the wild it grows across reef environments from the shallows right down to around 30 meters, which hints at a reasonable tolerance for varying light conditions. The colony form is typically massive and dome-shaped, with the characteristic star-patterned corallites arranged across its surface that give this group of corals their common name. Colors tend toward muted greens and browns, making this a more subtle presence in a tank compared to some of its flashier reef neighbors, but it contributes genuine texture and structure to a build-out. In the aquarium, moderate lighting and moderate flow suit it well, and it is considered reef safe with no notable aggression toward nearby corals beyond what you'd expect from any stony coral given enough space. Care is rated intermediate, so while it is not the most demanding coral on the shelf, it rewards keepers who already have stable reef chemistry dialed in rather than those still chasing consistency. Not a beginner coral, but a satisfying one once you have the fundamentals sorted.
