Indo Hologram Hammer

About this coral

Indo Hologram Hammer is an Indo “hammer” style LPS coral from the Euphyllia group. In practice, this coral is used as a centerpiece or movement-focused polyps display in reef tanks, prized for its long, flowing tentacles and the classic hammer/anchor-shaped tips seen in this Euphyllia type. Because “Indo Hologram Hammer” is often a trade name tied to appearance and sourcing rather than a single, always-identical scientific species, the care guidance below is provided as general Euphyllia (hammer-type) husbandry.

Features:

• Moderate light and medium flow help encourage steady polyp extension for Euphyllia hammer-style corals.
• Provide placement on rockwork with a few inches of space to reduce the risk of sweeper contact with neighbors.
• Maintain stable water chemistry—Euphyllia generally respond best when alkalinity, calcium, and magnesium are kept consistent.
• Feed is typically not required for healthy tanks; stable reef conditions support coral health over time.
• Give it time to acclimate after introduction or relocation, then fine-tune flow so it is not blasted directly.
• Semi-aggressive temperament: treat it as a coral that may sting nearby animals, especially in tight aquascapes.
