Green Hammer (2 Head )

Description:
Hammer corals are one of the most popular large-polyp stony (LPS) corals in the reef-keeping hobby. They are named for their distinctive hammer- or anchor-shaped tentacle tips, which can range in colors such as neon green, gold, purple, or a mix of shades. When fully extended, they create a flowing, wave-like appearance that adds movement and vibrant color to the reef aquarium.

Care Level: Moderate

Lighting:

• Moderate lighting (PAR 80–150).

• Too much light can cause bleaching, while too little can lead to poor expansion.

Flow:

• Moderate, indirect flow is ideal.

• Strong flow can damage their fleshy polyps, while too little flow may allow detritus to settle.

Placement:

• Place them in the mid to lower areas of the tank, depending on lighting.

• Provide enough space between them and other corals, as hammer corals have sweeper tentacles that can sting nearby corals.

Feeding:

• Photosynthetic via their zooxanthellae, but benefit from supplemental feeding.

• Can be target-fed small meaty foods such as mysis shrimp, brine shrimp, or coral foods 1–2 times per week.

Water Parameters:

• Temperature: 24–27°C

• Salinity: 1.024–1.026

• Alkalinity: 8–10 dKH

• Calcium: 400–450 ppm

• Magnesium: 1250–1350 ppm

• Nitrates: <10 ppm, Phosphates: <0.05 ppm

Aggression: Semi-aggressive – use caution with placement, as their sweeper tentacles can extend several centimeters.

Special Notes:

• Hammer corals are great centerpiece corals and are often kept alongside torch and frogspawn corals (also Euphyllia species).

• Avoid sudden changes in water parameters, as they are sensitive to instability.
