Product overview

The Hammer Coral is a premier Large Polyp Stony (LPS) specimen celebrated for its iconic, T-shaped tentacle tips that resemble miniature mallets, giving the colony a gorgeous, textured appearance. Available in both branching and wall growth habits and shimmering in brilliant shades of green, gold, pink, and purple, this magnificent coral adds incredible structural beauty and mesmerizing, flowing motion to any reef display.

Care & husbandry guidelines

• To keep your Hammer Coral expanding to its absolute fullest, provide moderate to high illumination balanced across blue and white spectra, paired with steady, medium water flow that gently sways the tentacles without beating against the flesh.
• While they derive abundant energy through photosynthesis via symbiotic zooxanthellae, routine target feedings of micro-plankton, mysis shrimp, or fine coral foods will noticeably enhance skeletal growth and color vibrancy.
• As a proudly aggressive member of the Euphyllia genus, they require generous personal spacing; ensure they are kept safely away from neighboring corals, as their extended sweeper tentacles can pack a potent sting to protect their territory.

How We Photograph Our Corals

Every WYSIWYG photo on The Twin Corals Shop is captured directly in our systems using meticulous settings to ensure absolute transparency. Our goal is straightforward: show the coral precisely as it appears in a well-maintained reef aquarium — never heavily filtered or artificially saturated.

Our Camera & Optics

• Camera: Google Pixel 10 Pro
• Lens / Mode: Macro focus lens with manual setting mode
• ISO: 50
• White Balance: Custom set between 9,000K–10,000K

This setup allows us to highlight the finest structural details — from delicate polyp extension and skeletal texture to subtle gradient color shifts — without washing out the true look of the animal.

Lighting We Shoot Under

• Fixtures: Nicrew Hyperreef Gen2 (100W or 150W depending on the system)
• Photo Spectrum Mix: White 5% · Violet 60% · UV 60% · Deep Blue 50%

Color Accuracy & Your Tank

By utilizing a targeted custom white balance, our photos closely mirror what you will see under a clean, balanced blue-leaning reef spectrum.

Keep in mind that corals are living organisms; their appearance can naturally shift from tank to tank depending on your specific water parameters, nutrient levels, lighting spectrum, and flow patterns. We strive to provide honest, dependable photos you can trust so your new coral looks right at home from day one.
