Common name: Blueberry Sea Fan

General information

Acropora echinata, commonly known as the Blueberry Sea Fan, is a species of small polyp stony (SPS) coral renowned for its vibrant blue coloration and unique growth form. This coral is highly sought after by aquarists for its aesthetic appeal and the dynamic structure it adds to the reef aquarium. It is characterized by its branching colonies with corallites that give it a spiky appearance, resembling a cactus.

Care

The Blueberry Sea Fan requires stable water conditions and intense lighting to thrive in captivity. It is a fast-growing species that benefits from strong water flow to prevent detritus accumulation and promote nutrient exchange. Calcium, alkalinity, and magnesium levels should be maintained within optimal ranges for SPS corals to support its skeletal growth. Feeding is not typically necessary, as it relies on photosynthesis, but occasional feeding of microplankton can promote health and coloration.

Symbiosis

Acropora echinata does not have any specific symbiotic relationships that are notable in the context of aquarium keeping. However, like many corals, it houses symbiotic algae known as zooxanthellae within its tissues, which provide the coral with nutrients through photosynthesis.

Habitat

This species is found in the Indo-Pacific region, particularly in shallow reef environments where it is exposed to strong light and water movement. In the wild, Acropora echinata can be found at varying depths, often forming dense thickets that serve as habitat for a variety of reef organisms.
