The Rainbow Hologram Hammer is one of the most visually striking Euphyllia variants in the hobby — its single head displaying an iridescent shimmer that shifts between electric greens, deep purples, pinks, and gold depending on your lighting angle. This isn't a standard hammer; the holographic color play is the result of selective aquaculture lineage that produces an effect rarely seen outside of high-end collector tanks. Single-head frags of this caliber move fast, and availability is always limited at The Coral Boutique.\u003c\/p\u003e\n\n\u003cp\u003eAs a single-head specimen, this frag gives your reef tank a focused, sculptural focal point while leaving room for it to branch and grow over time — Euphyllia ancora are known slow-and-steady growers that reward patient aquarists with genuinely impressive colonies. The long, flowing tentacles create a mesmerizing wave motion in moderate current, and the sweeping movement adds a dynamic energy to any saltwater aquarium. Hammer corals also have a satisfying personality: semi-aggressive sweeper tentacles keep neighboring corals honest, so placement matters and makes the aquascaping challenge worthwhile.\u003c\/p\u003e\n\n\u003ch3\u003eQUICK STATS \u0026amp; CARE GUIDE\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommon Name:\u003c\/strong\u003e Rainbow Hologram Hammer Coral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Size:\u003c\/strong\u003e Single head (approx. 1–1.5 inch polyp)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCare Level:\u003c\/strong\u003e Moderate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperament:\u003c\/strong\u003e Semi-aggressive (extended sweeper tentacles; keep 6+ inches from neighbors)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiet:\u003c\/strong\u003e Photosynthetic; benefits from occasional target feeding of mysis shrimp, coral-specific foods 1–2x per week\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReef Safe:\u003c\/strong\u003e With caution — maintain adequate spacing from other corals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Conditions:\u003c\/strong\u003e Temp 76–80°F | Salinity 1.025–1.026 | pH 8.1–8.3 | Alkalinity 8–10 dKH | Calcium 400–450 ppm | Magnesium 1250–1350 ppm | Moderate flow | Moderate lighting (PAR 75–150)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWHY BUY FROM THE CORAL BOUTIQUE?\u003c\/h3\u003e\n\n\u003cp\u003eEvery coral we ship is ethically sourced, fully quarantined, and conditioned in our Miami facility — we don't box anything until it's acclimated, healthy, and thriving under our care.
