Purple Staghorn Acropora Coral Frag
The Purple Staghorn Acropora is a classic SPS coral admired for its elegant branching structure and rich purple colouration. With long, slender branches and strong polyp extension, this coral creates height, movement, and a natural reef-crest aesthetic, making it a timeless addition to SPS-dominant reef aquariums.
Highly regarded for its fast growth and iconic staghorn form, Purple Staghorn Acropora is ideal for reef keepers looking to build dramatic structure while maintaining bold colour and visual balance.
Natural Habitat & Distribution
Acropora corals are native to the Indo-Pacific region, with populations found across:
-
The Great Barrier Reef, Australia
-
Indonesia
-
Fiji and Tonga
-
The Philippines
-
Central and Western Pacific reef systems
In the wild, staghorn Acropora species dominate shallow reef crests and upper reef slopes, where they are exposed to intense sunlight and strong, turbulent water movement. These conditions explain their need for high light and high flow in aquariums.
A Brief History
Staghorn Acropora are among the most recognisable reef-building corals in the world and have long been prized in the reef-keeping hobby for their rapid growth and branching architecture.
Purple varieties gained popularity as lighting technology improved, allowing aquarists to enhance and maintain deeper purple tones under stable, high-quality reef conditions.
Appearance & Growth
Classified as an SPS (Small Polyp Stony) coral, Purple Staghorn Acropora develops a fast-growing, open branching structure, with elongated branches and defined growth tips.
-
Slender staghorn branches
-
Rich purple to violet colouration
-
Strong polyp extension under stable conditions
Growth is fast in well-established reef systems.
Placement & Lighting
Purple Staghorn Acropora performs best under high lighting, closely replicating its natural reef-crest habitat.
-
Lighting: High
-
Best placed in the upper sections of the aquarium
-
Lower light may result in colour fading
Flow Requirements
Provide strong, random, turbulent flow to encourage healthy branch development, nutrient exchange, and polyp extension. Avoid direct laminar flow aimed at the coral.
Water Chemistry
Acropora corals require very stable water parameters. Maintain consistent levels of:
-
Calcium
-
Alkalinity
-
Magnesium
Along with low but stable nutrients and balanced trace elements. Regular testing and dosing are essential.
Feeding
Primarily photosynthetic, Purple Staghorn Acropora benefits from occasional supplemental feeding such as:
-
Fine powdered coral foods
-
Amino acids
-
Micro-plankton blends
Used sparingly, supplemental feeding can support colour depth and growth.
Temperament & Spacing
Acropora corals are generally peaceful, but their fast-growing branches require ample spacing to prevent contact with neighbouring SPS corals.
Frag Size & Natural Variation
