Common name: Psammocora contigua

General information

Psammocora contigua, commonly known as Porous Coral or Knobby Cactus Coral, is a small polyp stony (SPS) coral that is appreciated in the reefkeeping hobby for its hardiness and unique appearance. This species is characterized by its encrusting growth form and small, tightly packed corallites that give it a textured, knobby surface. The coral exhibits a variety of colors, ranging from brown to green, with some specimens displaying more vibrant hues under proper lighting.

Care

Psammocora contigua is a resilient SPS coral that can thrive in a range of conditions, making it suitable for intermediate to experienced reefkeepers. It prefers moderate to high lighting and water flow to maintain its health and coloration. Stable water parameters are crucial for its well-being, with particular attention to calcium, alkalinity, and magnesium levels to support its skeletal growth. Regular feeding with fine particulate foods can enhance its growth and vibrancy.

Symbiosis

While not known for hosting other organisms like some corals do, Psammocora contigua can contribute to the overall biodiversity of the reef aquarium by providing shelter and microhabitats for small invertebrates and microfauna.

Habitat

Psammocora contigua is found in a variety of reef environments, from shallow lagoons to deeper slopes. It is adaptable to different light conditions in the wild, which is reflected in its flexibility in the aquarium setting. This species is distributed across the Indo-Pacific region, where it contributes to the complex structure of coral reefs.
