Hump Coral

About

Hump Coral (Porites horizontalata) is one of those reef builders that rewards a closer look. Rather than growing in a single predictable shape, colonies develop as a combination of encrusting plates and twisted, intertwining branches that fuse and loop back on themselves in ways that look almost architectural. The individual corallites are organized into small clusters separated by distinct ridges, which gives the surface a subtly patterned texture that stands apart from other Porites. Coloration runs toward pale brown across most of the colony, with cream tones appearing at branch tips and plate edges. In particularly shallow, well-lit conditions, colonies can take on brighter hues, though muted earth tones are the norm. In the wild this species occupies shallow reef environments where light is strong and water movement keeps nutrients circulating. In the aquarium that translates to a need for high lighting and moderate flow to keep the tissue healthy and the growth form developing properly. Porites in general are considered hardier than many reef corals, but this species sits comfortably in the intermediate care bracket, making it a reasonable choice for a hobbyist who has already gotten comfortable with the basics of reef keeping and wants to add some genuine structural interest to the aquascape.
