False Knob Coral

About

False Knob Coral (Favites valenciennesii) is a large-polyp stony coral with a wide natural range stretching from Japan down to Australia and across from Mozambique to Fiji, turning up anywhere from the shallows to depths of around 40 meters. Like other members of the Favites group, it forms a rigid, encrusting to dome-shaped colony where individual corallites share walls, giving the surface that characteristic honeycomb or brain-like texture that distinguishes these corals from similar genera like Favia, which have separate corallite walls. Coloration tends to run in earth tones, greens, browns, and grays, sometimes with contrasting oral disc colors when the polyps are extended. In the aquarium, this coral is considered an intermediate-level keeper rather than a beginner's coral. It appreciates moderate lighting and moderate water flow, conditions that reflect its natural habitat across a variety of reef zones. Given stable water chemistry and consistent conditions, it is a reasonably durable coral, but it will not tolerate neglect the way some soft corals might. Placement matters. It needs enough space that its sweeper tentacles, which it extends at night, won't bother neighbors. A solid choice for a hobbyist ready to move beyond the more forgiving beginner species.
