Giant Star Coral

About

Giant Star Coral (Moseleya latistellata) is one of the more unusual stony corals you'll come across, and not just because of its looks. In the wild it occupies a niche that most reef-building corals avoid entirely. Turbid, silty water with muddy bottoms, sometimes even in zones that get exposed at low tide. That kind of resilience translates well to the aquarium, and it's generally considered a beginner-friendly choice among LPS corals. The colony typically grows as a flat, disc-like or submassive form, and what really sets it apart structurally is its arrangement of corallites: one large central polyp, which can reach a considerable size, ringed by progressively smaller angular daughter corallites arranged in a concentric pattern. It gives the whole colony a very geometric, almost engineered appearance. Colors run from pale to deep green or brown, nothing flashy, but there's a quiet elegance to the patterning. One behavioral detail worth knowing is that the tentacles only extend on dark nights, so if you want to catch this coral fully open, you'll need to check on it after lights-out. It does best under moderate lighting and appreciates low, gentle flow rather than strong currents.
