Rice Coral

About

Rice coral (Montipora verrucosa) gets its common name from the distinctive bumpy surface that covers every inch of the colony. Those rounded nodules, called verrucae, are the defining feature you use to identify this species. Tucked between the verrucae are the tiny individual polyps, which occasionally extend bright blue or green tentacles during daylight hours, adding a flash of life to what might otherwise look like a textured stone. Colony shapes vary quite a bit: you might find encrusting sheets spreading across rock, chunky submassive mounds, upright columns, or broad laminar plates, sometimes all from the same parent population depending on light and flow conditions. Base coloration runs from blue to brown, solid or mottled, and the blue morphs in particular can shift toward purple under certain aquarium lighting. In the wild, this coral inhabits upper reef slopes and lagoons across a wide swath of the Indo-Pacific, from shallow surge zones down to considerable depth. In the aquarium it wants intense lighting and robust, consistent flow to thrive. It is not a coral for casual setups or beginners. Stable, mature reef chemistry is really the minimum starting point. Get the conditions right, though, and it can develop into an architecturally interesting centerpiece over time.
