Common name: Acrozoanthus Australiae

General information

Acrozoanthus australiae, commonly known as the Australian Tube Zoanthid or Stick Polyp, is a unique and captivating species of zoanthid that is highly sought after by reef aquarium enthusiasts. Unlike most zoanthids that form encrusting mats, Acrozoanthus australiae grows in a tube-like structure, which gives it a distinctive appearance in the reef aquarium.

This species is known for its hardiness and ability to adapt to various lighting conditions, making it a popular choice for both novice and experienced aquarists. The polyps of Acrozoanthus australiae are typically brown to green with a fluorescent hue that can be enhanced under actinic lighting.

Care

Acrozoanthus australiae requires moderate care. It thrives in moderate to high lighting and moderate water flow. While it can tolerate a range of lighting conditions, providing a stable environment with consistent water quality is crucial for its growth and coloration. It is important to place them in an area of the tank where they will not be overshadowed by other corals, as they need sufficient light to photosynthesize effectively.

Feeding is not strictly necessary as they contain symbiotic algae known as zooxanthellae that provide most of their nutritional needs through photosynthesis. However, supplemental feeding with zooplankton can promote faster growth and more vibrant colors.

Symbiosis

Acrozoanthus australiae does not have any well-known symbiotic relationships like those seen in clownfish and anemones. However, its tube-like structure can provide microhabitats for small invertebrates and serve as a refuge for tiny reef creatures.

Habitat

Native to the waters of Australia, Acrozoanthus australiae is typically found attached to rocky substrates or coral rubble in shallow waters. They are often observed in areas with moderate water movement, which helps to keep their polyps free of debris and supplies them with nutrients.
