ACI Prince of Darkness Hammer Coral

ACI Prince of Darkness Hammer Coral is a hammer coral with broad, hammer-shaped polyp tips and flowing tissue. Its movement and coloration are best displayed when the coral is given stable reef conditions, suitable light, and gentle indirect water movement.

Hammer Coral Care

Hammer corals respond best to stable reef conditions. Place this coral where its fleshy polyps can sway without being folded over or driven against the skeleton by a direct stream. Acclimate it gradually to your lighting and leave open space around the colony for nighttime sweeper tentacles.

Placement and Acclimation

Branching hammer corals grow as separate heads on a branching skeleton; protect the soft tissue from abrasion when handling or positioning the frag. Start at the lower end of the stated light range, then adjust gradually while watching polyp extension and tissue condition. Keep the coral separated from neighbors that could be reached by its sweepers.

Maintain consistent salinity and alkalinity, and avoid sudden changes in light or flow. Do not force food into retracted polyps; stable conditions and appropriate placement matter more than heavy feeding.
