Common name: Pore coral

General information

Montipora nodosa, commonly known as Nodular Montipora or Rice Coral, is a small polyp stony (SPS) coral that is popular among reef aquarium enthusiasts for its unique growth form and coloration. This species is characterized by its encrusting to nodular growth, where the coral develops small, rounded protrusions across its surface, giving it a textured appearance.

Montipora nodosa can exhibit a range of colors, from pale browns to vibrant greens and purples, often with contrasting polyp colors. This variability makes it a visually appealing addition to any reef tank, where it can add both structure and color diversity.

Care

As with many SPS corals, Montipora nodosa requires stable water conditions to thrive. It prefers moderate to high lighting and water flow, which helps to keep the coral free from sediment and provides the necessary nutrients for growth. Hobbyists should maintain calcium, alkalinity, and magnesium levels within the appropriate ranges to support the coral's skeletal development.

Feeding is not typically necessary for Montipora nodosa, as it harbors zooxanthellae, symbiotic algae that provide the majority of its nutritional needs through photosynthesis. However, supplemental feeding with fine particulate foods can benefit growth and coloration.

Symbiosis

Montipora nodosa, like many corals, has a symbiotic relationship with zooxanthellae, which live within its tissues. These algae perform photosynthesis, producing oxygen and organic compounds that nourish the coral. In return, the coral provides the algae with a protected environment and access to sunlight.

Habitat

Montipora nodosa is found in the Indo-Pacific region, typically in shallow reef environments where sunlight is abundant. It is often seen on reef slopes and in lagoons, where it can grow on both hard substrates and overhangs. This species is adaptable to various light and flow conditions in the wild, which is reflected in its care requirements in the aquarium setting.
