Common name: Branched cup coral

General information

Blastomussa wellsi, commonly known as Pineapple Coral or Blasto Coral, is a species of large polyp stony (LPS) coral that is popular among reef aquarium hobbyists for its vibrant colors and ease of care. It is characterized by its round, fleshy polyps that extend from a calcified base. The polyps can come in a variety of colors, including red, green, blue, and purple, often with contrasting centers or 'mouths' that add to their visual appeal.

Care

Blastomussa wellsi is considered a hardy coral that can thrive in a range of lighting conditions, from moderate to low. It prefers indirect lighting and moderate water flow to prevent sediment from settling on its polyps, which can cause irritation. This coral benefits from the addition of calcium, alkalinity, and magnesium supplements to maintain robust skeletal growth. Target feeding with microplankton or finely minced meaty foods can promote faster growth and more vibrant colors.

Symbiosis

While not known for hosting fish or invertebrates, Blastomussa wellsi can contribute to the overall health of the reef aquarium by providing shelter and territory for small, peaceful creatures. Its structure offers a safe haven for tiny organisms and can be part of a diverse and balanced reef ecosystem.

Habitat

Blastomussa wellsi is found in the Indo-Pacific region, typically in sheltered lagoons and reef slopes. It is often located at depths ranging from 5 to 30 meters, where it can grow in both solitary and colonial forms. In the aquarium, it should be placed in an area with low to moderate flow and lighting to mimic its natural environment.
