🌈 Prismfire Acropora

Acropora tenuis (Rainbow Colony)

🔹 Quick Stats

• Care Level: Moderate to Advanced

• Temperament: Peaceful

• Colour Form: A vivid rainbow gradient across each branch — combining shades of pink, orange, yellow, green, and blue. Under actinic or blue-dominant lighting, each hue fluoresces, creating a dazzling, multi-coloured ultra effect.

• Water Conditions: 24–27 °C, dKH 8–12, pH 8.0–8.4, sg 1.024–1.026

• Family: Acroporidae

• Lighting: Moderate to high (to maximise vibrant rainbow coloration)

• Supplements: Calcium, Magnesium, Trace Elements, Amino Acids

• Water Flow: Moderate — sufficient for healthy polyp extension

• Placement: Mid to upper reef levels for optimal light exposure

🧬 Overview

The Prismfire Acropora is a rare ultra morph of Acropora tenuis, prized for its full spectrum of vibrant colors. Each branch transitions smoothly through multiple shades, creating a living rainbow that captivates the eye. The colony’s branching structure allows full polyp extension, enhancing fluorescence and dynamic movement in the tank.

This ultra rainbow morph is highly sought-after by collectors looking for a one-of-a-kind centerpiece that brings maximum visual impact to any reefscape.

🍽️ Feeding & Care

While photosynthetic, this Acropora benefits from targeted supplemental feeding 1–2 times per week. Offer fine particulate foods, coral amino acid blends, or phytoplankton to enhance color intensity, promote polyp extension, and support steady growth. Maintaining stable water parameters is essential for long-term health and ultra coloration.

📈 Optimal Parameters

• Alkalinity (dKH): 8–12

• Calcium (Ca): 420–460 ppm

• Magnesium (Mg): 1250–1350 ppm

• Nitrate (NO₃): 0–10 ppm

• Phosphate (PO₄): 0–0.05 ppm

📍 Placement

Position in moderate to high lighting with gentle, steady flow. Allow enough space around the colony for polyp extension and avoid aggressive neighbours. Under blue-dominant lighting, each color fluoresces vividly, creating a stunning rainbow effect that makes the colony a true ultra centerpiece.
