💚💙💛 Favia spec. “Neon Halo Colony”
Brain Coral – Large Polyp Colony With Yellow Mouths and Iridescent Green-Blue Rings (WYSIWYG Specimen)
🔹 Quick Stats
Care Level: Easy
Temperament: Semi-aggressive (short sweeper tentacles at night – allow space)
Colour Form: The “Neon Halo” morph displays bright yellow mouths surrounded by electric green rings, fading outward into deep turquoise and blue rims that shimmer under actinic lighting. Under full-spectrum light, the contrast between the yellow centres and blue-green edges gives a crisp, three-dimensional “halo” look — vibrant, luminous, and strikingly defined.
Water Conditions: 24–26 °C, dKH 7.5–9, pH 8.0–8.4, sg 1.024–1.026
Family: Faviidae
Lighting: Moderate (PAR 70–120)
Water Flow: Gentle to moderate
Placement: Lower to mid-rockwork or sandbed, with clearance for expansion
🧬 Overview
The Favia “Neon Halo Colony” is a classic yet high-impact coral, prized for its clean symmetry and fluorescent contrast. Each polyp glows with a defined yellow core encircled by radiant green and blue tissue — a geometry that adds rhythm and balance to any reefscape.
Each WYSIWYG colony is hand-selected for:
-
Precise, high-definition colour zoning
-
Healthy, plump polyps and uniform structure
-
Excellent colour stability under varied spectrums
-
Strong tissue coverage and clean skeletal base
Ideal for aquarists seeking a colourful, low-maintenance centrepiece that thrives under standard reef parameters.
🍽️ Care & Feeding
Favia corals are photosynthetic but appreciate supplemental feeding for optimal growth.
Feed 1× weekly with:
-
Finely minced mysis or brine shrimp
-
Reef-roids or micro-coral blends
Target-feed gently with reduced flow to allow full polyp extension.
📈 Optimal Parameters
| Parameter | Ideal Range |
|---|---|
| Alkalinity (dKH) | 7.5–9 |
| Calcium (Ca) | 420–450 ppm |
| Magnesium (Mg) | 1300–1400 ppm |
| Nitrate (NO₃) | 5–15 ppm |
| Phosphate (PO₄) | 0.03–0.10 ppm |
📍 Placement
Place in moderate lighting and flow zones where its polyps can extend slightly at night.
Avoid direct contact with other LPS — Favia extend short sweepers that can sting nearby tissue.
Maintain stable parameters for best colour retention.
