🌈🔥 Acropora millepora “Rainbow” – Colonies (S / M / L)
Acropora millepora – Multicolour Premium SPS Coral With Intense Polychromatic Fluorescence (Aquarium-Grown Colonies)
🧬 Overview
The Acropora millepora “Rainbow” is a breathtaking SPS coral featuring multi-hued pigmentation across its branches — blending rose pinks, tangerine oranges, neon yellows, turquoise greens, and electric blues in one radiant structure.
Each colony is tank-grown and fully conditioned, ensuring vibrant colour retention, healthy polyp extension, and fast growth under stable reef conditions.
Available in three size grades:
-
S (Small): Compact, multi-branch starter colony – perfect for rapid growth and colour development
-
M (Medium): Balanced, structured colony with distinct colour zones
-
L (Large): Mature, high-impact display colony – bursting with colour and movement
📸 Photos shown are examples – each colony displays its own natural mix of rainbow tones, but all share the same morph and brilliance.
🔹 Quick Stats
Care Level: Moderate to Advanced
Temperament: Peaceful (allow spacing from other SPS)
Colour Form: A true rainbow Acropora combining pink, orange, yellow, turquoise, and blue hues across the branches and tips. Under daylight, the coral shows soft pastel transitions; under actinic blues, it ignites with high-contrast fluorescence and metallic undertones.
Lighting: High (PAR 250–400)
Water Flow: Strong and alternating
Placement: Upper rockwork or high-flow exposed areas
💡 Growth & Colour
This millepora morph grows in dense, bushy clusters with short, even radial corallites — ideal for capturing light from all angles.
Expect:
-
fast vertical and lateral growth under stable SPS parameters
-
layered colour gradients that intensify with light spectrum tuning
-
vivid fluorescence enhanced by hybrid or LED lighting
Stable nutrient levels and trace element balance (especially iron and manganese) help maintain full rainbow expression.
🍽️ Care & Feeding
Primarily photosynthetic, but benefits from occasional feeding. Offer:
-
fine powdered coral foods or amino acids
-
microplankton blends (1–2× weekly)
Feeding helps sustain rich pigmentation and enhances new growth tips.
📈 Optimal Parameters
| Parameter | Ideal Range |
|---|---|
| Alkalinity (dKH) | 7.5–8.5 |
| Calcium (Ca) | 420–450 ppm |
| Magnesium (Mg) | 1250–1400 ppm |
| Nitrate (NO₃) | 2–10 ppm |
| Phosphate (PO₄) | 0.02–0.08 ppm |
📍 Placement
Position the coral in high light and strong, alternating flow to develop the full spectrum of rainbow pigmentation.
Allow open space for upward and outward branching.
