🧬 Overview
The Rainbow Acanthastrea lowdwensis frag is a true showstopper for any LPS collection. Its multicolored polyps bring dynamic visual interest and a vibrant, living spectrum to the reef. This coral thrives in stable, low-stress environments, where gentle flow and balanced lighting allow the full range of colors to develop and intensify over time.

🍽️ Care & Feeding
Though photosynthetic, this coral benefits from target feeding 1–2 times per week. Offer finely minced meaty foods such as mysis, brine shrimp, or powdered coral diets like Reef Roids. Feeding during low flow or after lights-out encourages polyp extension and enhances the vibrancy of each color.

⚠️ Note: Sweeper tentacles can extend at night, so provide adequate spacing from nearby corals to avoid stinging.

📈 Optimal Parameters

• Alkalinity (dKH): 8–11

• Calcium (Ca): 420–460 ppm

• Magnesium (Mg): 1250–1350 ppm

• Nitrate (NO₃): 2–10 ppm

• Phosphate (PO₄): 0.01–0.05 ppm

📍 Placement
Position on stable rock or sandbed in lower-to-mid reef areas with gentle, indirect flow. Blue-dominant or mixed spectrum lighting will maximize the rainbow effect, creating a vibrant focal point in your aquarium.
