Purple Tip Acropora granulosa
A beautiful smooth-skinned, tabling Acropora with an established colony colouration of turquoise through the body, finished with contrasting purple growth tips.
Our current frags are displaying a noticeably more golden body colour following fragging and establishment. As they settle and grow, colouration may develop and change depending on lighting, nutrients, water chemistry and individual aquarium conditions.
Acropora granulosa develops an elegant, relatively smooth branching structure and, given time, forms an attractive tabling growth pattern.
Care Level: Advanced
Lighting: Moderate to High
Flow: Moderate to High, indirect and varied
Placement: Middle to Upper areas of the aquarium
Temperament: Peaceful, but allow adequate room for growth
Frag Size: Approx. 20mm
As with all SPS corals, colouration can vary considerably between systems. Stable water parameters, suitable lighting and strong, varied water movement are recommended for best growth and colour.
🪸 Coral Care Guide

💧 Water Parameters
Purple Goniopora thrive in stable reef aquariums with consistent water chemistry.
Recommended Parameters
- Stable Alkalinity
- Calcium
- Magnesium
- Stable Nitrate & Phosphate levels
- Trace elements including iodine and iron are beneficial.
Avoid ultra-low nutrient systems, as Goniopora generally perform best in mature, nutrient-balanced aquariums.
🍤 Feeding & Nutrition
Purple Goniopora benefit from regular supplemental feeding to encourage long-term health, vibrant colour and strong polyp extension.
Recommended Foods
- Fine powdered coral foods
- Phytoplankton
- Micro-plankton blends
- Small particulate coral foods
Feeding Frequency
Feed lightly but consistently 2–3 times per week.
🌊 Placement & Acclimation
Purple Goniopora appreciate thoughtful placement and a gentle introduction to your aquarium.
Placement
- Lower to middle areas of the aquarium.
- Allow plenty of space for full polyp extension.
- Avoid direct contact with aggressive or stinging corals.
- Prevent polyps from rubbing against rockwork.
Lighting
Medium lighting is recommended.
Too much light may cause the coral to retract, while insufficient lighting can reduce extension.
Light acclimation is recommended whenever introducing a new specimen.
Water Flow
Provide moderate, indirect flow that keeps the polyps gently swaying.
Avoid strong, direct flow, which may prevent full extension.
Random, alternating flow patterns generally produce the best results.
🌍 Natural Habitat
Purple Goniopora originate from the Indo-Pacific region and are commonly found throughout:
- Indonesia
- Australia's Great Barrier Reef
- Fiji
- Tonga
- Papua New Guinea
- Central and Western Pacific reef systems
In the wild they inhabit sheltered lagoon environments and protected reef zones with moderate lighting, gentle water movement and nutrient-rich conditions.
Once considered difficult to keep, advances in modern reef keeping—including improved lighting, flow control and nutrition—have made healthy, aquacultured Goniopora far more reliable long-term additions to today's reef aquariums.
⭐ ReefGro Expert Advice
Purple Goniopora is one of our favourite LPS corals thanks to its elegant movement and rich purple colouration.
When fully extended, hundreds of delicate tentacles create constant movement that contrasts beautifully with SPS colonies and other fleshy LPS corals, making it an excellent centrepiece for mixed reef aquariums.
For the best results:
- Introduce the coral slowly using light acclimation.
- Maintain stable water chemistry.
- Feed regularly with fine particulate foods.
- Avoid placing it where neighbouring corals can sting the extended polyps.
- Be patient during acclimation—healthy Goniopora often become more fully extended as they settle into stable conditions.
