Common name: purple tipped acropora

General information

Acropora tenuis, commonly known as Blue Acropora or Slender Acropora, is a species of small polyp stony (SPS) coral that is popular among reef aquarium enthusiasts for its striking coloration and intricate branching growth form. This coral is known for its resilience and relatively fast growth rate compared to other SPS corals, making it a favorite for aquascapers looking to create dynamic reef structures.

Care

Acropora tenuis requires stable water conditions with strong lighting and moderate to high water flow to thrive in captivity. It is important to maintain consistent levels of calcium, alkalinity, and magnesium to support its skeletal growth. Regular feeding with microplankton or coral foods designed for SPS corals can promote health and coloration.

Symbiosis

Like many Acropora species, A. tenuis may host a variety of symbiotic organisms, including certain species of commensal crabs and shrimps that protect the coral from pests and help keep it clean. Additionally, it harbors zooxanthellae, symbiotic algae that provide the coral with nutrients through photosynthesis.

Habitat

Acropora tenuis is found in the Indo-Pacific region, typically in shallow reef environments where it forms part of the complex reef structure. It can be found at varying depths, often between 5 to 20 meters, where it receives ample sunlight to support its symbiotic algae.
