Blue & Gold Stem Hammer Coral

The Blue and Gold Stem Hammer Coral is a standout euphylliid variety that holds a prized position in modern mixed reef aquariums. Belonging to the large polyp stony family, this branching specimen combines classic hammer-shaped polyp tips with distinctive coloration along the tentacles. This piece measures approximately 7cm and features healthy, well-developed tissue extending over a solid skeletal base.

In the aquarium, the tentacles expand generously during the photoperiod, showcasing contrasting tones with rich gold running through the stems beneath soft blue tips. As water moves across the colony, the hammer-shaped ends sway steadily, adding essential kinetic movement to the aquascape. At night, the polyps retract slightly into the skeleton, though a healthy specimen remains fleshy and well-attached around the perimeter of each head.

Care requirements are straightforward for an established LPS system. Position this hammer in the lower to middle section of the rockwork where it receives moderate lighting around 75 to 150 PAR and gentle, indirect water flow. Excessive or direct current can tear the soft tissue against the sharp skeleton, so turbulent or erratic water motion is preferable to linear flow. Maintain standard reef parameters with calcium at 400 to 450 ppm, alkalinity between 8 and 9 dKH, and magnesium around 1300 to 1350 ppm. Like all euphylliids, it packs a potent sting with sweeper tentacles that can extend several inches at night, so provide ample clearance from neighboring corals, and acclimate gradually under reduced lighting.
