Tri Colour Toxic Green Splatter Hammer Coral Frag
The Tri Marble Toxic Green & Purple Hammer is a standout Euphyllia coral featuring an eye-catching blend of neon toxic green, deep purple accents, and intricate marbling across the tentacles. This complex colour mix, combined with classic hammer-shaped tips and flowing movement, makes it a true feature coral for modern reef aquariums.
With its bold contrast and strong fluorescence, this hammer coral delivers maximum visual impact while retaining the dependable care profile Euphyllia is known for.
Natural Habitat & Distribution
Hammer corals (Euphyllia ancora / Euphyllia paraancora) are found throughout the Indo-Pacific, including:
-
Indonesia
-
Australia (Great Barrier Reef)
-
Fiji and Tonga
-
The Philippines
They naturally inhabit sheltered reef slopes and lagoon environments, where lighting is moderate and water movement is gentle to moderate.
A Brief History
Hammer corals have long been a cornerstone of the reef hobby thanks to their movement, resilience, and distinctive form. As LED lighting technology advanced, highly marbled and multi-colour morphs gained popularity for their depth, contrast, and fluorescence.
Tri-colour marbled variants, combining toxic greens with rich purples, are especially sought after for their rarity and ability to stand out even in densely stocked reefs.
Appearance & Growth
Classed as an LPS (Large Polyp Stony) coral, the Tri Marble Toxic Green & Purple Hammer features long, fleshy tentacles ending in pronounced hammer-shaped tips.
-
Intense toxic green base colour
-
Deep purple marbling and highlights
-
Strong fluorescence under blue lighting
-
Excellent polyp extension when healthy
Growth is steady in stable systems, with heads dividing over time.
Placement & Lighting
This hammer coral performs best under moderate lighting.
-
Lighting: Medium
-
Best placed in the mid to lower areas of the aquarium
-
Excessive light may cause colour stress or fading
Flow Requirements
Provide gentle to moderate, indirect flow. Tentacles should sway naturally without being blasted by direct current.
Water Chemistry
Stable reef parameters are essential for long-term success. Maintain consistent levels of:
-
Calcium
-
Alkalinity
-
Magnesium
Along with stable salinity and temperature. Regular testing and water changes are recommended.
Feeding
While photosynthetic, this hammer coral benefits from occasional feeding such as:
-
Small meaty foods (mysis, brine shrimp)
-
LPS-specific coral foods
Feeding once or twice weekly can enhance growth and colour intensity.
Temperament & Spacing
Hammer corals are semi-aggressive and may extend sweeper tentacles at night.
-
Allow adequate spacing around the frag
-
Avoid placing too close to other Euphyllia or delicate corals
Frag Size & Natural Variation
-
Frag size: Typically 1–2 heads
-
Marbling patterns and colour balance will vary naturally between frags and may shift depending on lighting and tank conditions.

💧 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.
