Hump Coral

About

Hump Coral (Porites arnaudi) is a plating species that forms some genuinely architectural growth patterns in the wild. Colonies spread out as flat, stacked plates arranged in tiers or loose whorls, giving mature specimens a layered, almost terraced profile. The corallites themselves are compact and deeply set into the skeleton, which gives the surface a dense, pitted texture quite different from the more loosely structured Porites you might already know. Coloration tends toward muted tones, pale brown or a soft greenish-grey, and the plate margins are typically lighter than the rest of the colony, which helps define that tiered structure visually. In the wild this species occupies upper reef slopes and rocky foreshores that take a real beating from wave surge, so it's built for turbulent, well-oxygenated conditions. In the aquarium, moderate flow is the target rather than the maximum blast you might assume from its natural habitat, but good gas exchange and consistently high light are genuinely important for keeping it healthy. It falls into the intermediate care bracket, so it's not a beginner coral, but a keeper with a stable, mature reef system and solid husbandry habits should find it manageable and rewarding to grow out.
