Rosie Purple Hammer Coral
The Rosie Purple Hammer is an elegant and highly desirable LPS coral, showcasing rich purple to lavender tones paired with the classic hammer-shaped tentacles that Euphyllia are famous for. When fully extended, this coral delivers beautiful, rhythmic movement, adding both colour depth and natural flow to the reef aquarium.
With its refined colouration and dependable nature, the Rosie Purple Hammer is an excellent choice for reef keepers looking to add a softer yet striking focal coral to mixed or LPS-dominant systems.
Natural Habitat & Distribution
Hammer corals (Euphyllia ancora / Euphyllia parancora) originate from the Indo-Pacific region and are commonly found across:
-
Indonesia
-
Australia’s Great Barrier Reef
-
Fiji and Tonga
-
The Philippines
-
Central and Western Pacific reef systems
In the wild, hammer corals inhabit protected reef slopes and lagoon environments where lighting is moderate and water movement is gentle to moderate.
A Brief History
Euphyllia corals have long been mainstays of the reef hobby thanks to their flowing movement, adaptability, and visual appeal. Purple-toned hammer morphs have grown in popularity as modern lighting systems enhanced their colour saturation and fluorescence, making varieties like the Rosie Purple Hammer especially sought after for elegant reef layouts.
Appearance & Growth
Classified as an LPS (Large Polyp Stony) coral, the Rosie Purple Hammer features sturdy skeletal branches topped with fleshy, hammer-shaped tentacles.
-
Rich purple to lavender coloration
-
Distinct hammer-shaped tentacle tips
-
Smooth, flowing movement in moderate flow
-
Subtle to moderate fluorescence under blue lighting
Growth occurs through branching, with additional heads forming over time in stable conditions.
Placement & Lighting
Hammer corals thrive under moderate lighting and thoughtful placement.
-
Lighting: Medium
-
Best placed in the lower to mid areas of the aquarium
-
Acclimation recommended when increasing light intensity
Flow Requirements
Provide moderate, indirect flow.
-
Enough movement to keep tentacles gently swaying
-
Avoid strong, direct laminar flow which may cause tissue damage
A gentle, alternating flow pattern works best.
Water Chemistry
Stable water parameters are essential for Euphyllia success.
Maintain consistent levels of:
-
Alkalinity
-
Calcium
-
Magnesium
Hammer corals prefer low to moderate nutrients and benefit from overall system stability rather than frequent parameter adjustments.
Feeding
Primarily photosynthetic, Rosie Purple Hammer corals benefit from occasional supplemental feeding.
-
Mysis shrimp, brine shrimp, finely chopped seafood
-
LPS pellets or coral-specific meaty foods
Feed sparingly 1–2 times per week when tentacles are extended.
Temperament & Spacing
Hammer corals are semi-aggressive and may extend sweeper tentacles.
-
Allow several inches of space from neighbouring corals
-
Avoid placing near delicate or easily stung species
-
Can coexist with other Euphyllia when given adequate room
Frag Size & Natural Variation
-
Frag size: Typically 1–2 heads (unless otherwise stated)
-
Colour tone and tentacle shape may vary depending on lighting and tank conditions.
