Common name: Column coral

General information

Porites rus, commonly known as Hump Coral, is a species of stony coral that is quite distinctive due to its finger-like projections and massive, dome-shaped colonies. It is a slow-growing coral but can eventually form significant structures within the reef. Porites rus is known for its resilience and ability to thrive in a variety of environmental conditions, making it a suitable candidate for reef aquariums.

Care

Hump Coral requires moderate to high lighting and moderate water flow to thrive in captivity. It is important to maintain stable water parameters, particularly calcium and alkalinity levels, to support its skeletal growth. Porites rus is photosynthetic, hosting zooxanthellae in its tissues that provide most of its nutritional needs through photosynthesis. However, it can also benefit from occasional feedings of microplankton or other fine particulate foods.

Symbiosis

Porites rus does not have the same level of symbiotic relationships as some other corals, but it can serve as a substrate for various small invertebrates and algae. Its structure provides shelter and a surface for attachment, contributing to the biodiversity of the reef ecosystem.

Habitat

This coral species is found in a range of reef habitats, from shallow lagoons to deeper slopes, typically in the Indo-Pacific region. It can withstand various levels of water movement, from calm waters to strong currents, and is often seen in areas with high sedimentation.
