Single Head Rainbow Hammer

Overview:

The Rainbow Hammer coral (Fimbriaphyllia paraancora) is a captivating branching coral known as the “holy grail” among Euphyllia species. It features a unique genetic coloration blend that creates a dynamic visual display under aquarium lighting. Its branching growth form makes it easier to frag and maintain compared to wall types, making it a prized yet sustainable reef addition.

Colorization:

This coral displays a striking multi-tonal mix of gold, orange, and copper stalks accented with vibrant neon tips that can range from green to purple or pink. Under high-actinic (blue) light, its colors glow and shift, producing a mesmerizing “lava-lamp” effect that enhances any reef tank’s aesthetics.

Size:

This offering is a single head specimen, ideal for aquarists seeking to start or expand their collection with a manageable and striking coral piece.

Lighting:

Moderate lighting between 125–200 PAR is recommended. Excessive light can bleach the gold hues to pale yellow, while too little light may cause the colors to dull to muddy green. Balanced lighting conditions ensure optimal coloration and health.

Water Flow:

Prefers medium, indirect water movement that allows the tentacles to sway rhythmically. Strong or direct flow may cause tentacles to retract, negatively impacting coral health.

Feeding:

The Rainbow Hammer benefits from weekly supplemental feedings with mysis shrimp or specialized LPS pellets. Nonetheless, it primarily derives energy from photosynthesis under proper lighting.

Aggressiveness:

This coral is peaceful but requires sufficient space to avoid contact with neighboring corals due to its extended tentacles.

Care Level:

Moderate care is needed, including maintaining stable alkalinity and calcium levels. It is sensitive to sudden changes in salinity, so stable water parameters are essential for thriving.
