Common name: Cauliflower coral

General information

The Cauliflower Coral, Pocillopora verrucosa, is a small polyp stony (SPS) coral known for its hardiness and branching growth form resembling a cauliflower. It is a popular choice among reef aquarium hobbyists due to its relatively fast growth rate and ease of care compared to other SPS corals. This species exhibits a variety of colors, including pink, green, and brown hues, depending on the lighting and water conditions in the aquarium.

Care

Cauliflower Coral thrives in well-lit aquariums with strong water flow, which helps to deliver nutrients and remove waste from the coral's surface. It is important to maintain stable water parameters, particularly calcium and alkalinity levels, to support its skeletal growth. Regular feeding with microplankton or coral foods designed for SPS corals can promote health and coloration.

Symbiosis

Pocillopora verrucosa is known for its symbiotic relationship with small crustaceans, particularly the Pocilloporid crab (Trapezia spp.). These crabs live within the branches of the coral and provide protection against predators and parasites. In return, the coral offers shelter and food in the form of mucus and plankton caught by the coral.

Habitat

In the wild, Cauliflower Coral is commonly found in shallow reef environments, often in areas with strong wave action. It is widely distributed across the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific Ocean. This species can form extensive colonies and is an important contributor to reef building and the overall structure of coral reef ecosystems.
