Rainbow Hammer - Single Head

Rainbow Hammer Coral Frag (Euphyllia paraancora)

Description:
The Rainbow Hammer Coral is a true centerpiece LPS coral, showcasing a mesmerizing blend of gold, pink, teal, and green hues across its distinctive hammer-shaped tentacles. Under blue or actinic lighting, its tips shimmer with iridescent rainbow tones, creating an incredible visual contrast and dynamic movement within the reef. Each frag brings vibrant color and motion to your aquarium, making it a standout addition for collectors and reef enthusiasts alike.

This branching Euphyllia variety is aquacultured for resilience and adapts well to established reef systems with stable parameters.

Care Level: Easy to Moderate
Temperament: Semi-aggressive (can extend sweeper tentacles at night)
Placement: Mid to lower regions of the tank with space for full polyp expansion and to prevent stings to neighboring corals.

Ideal Water Parameters

Feeding & Nutrition:

Like most Euphyllia corals, the Rainbow Hammer hosts symbiotic zooxanthellae that provide energy through photosynthesis. For optimal growth and vibrancy, supplement with occasional target feedings of mysis shrimp, brine shrimp, or high-quality coral foods 1–2 times per week.

Notes:

• Provide several inches of clearance from other corals to avoid sweeper tentacle contact.

• Prefers gentle, alternating flow to allow tentacle movement without excessive force.

• Avoid placing under intense direct light to prevent tissue retraction.

• Compatible with other Euphyllia species (torch, frogspawn, hammer) if given adequate spacing.
