Nuclear Yellow Collector Tenuis with Extreme Fluorescence
🔹 Quick Stats
Care Level: Advanced
Temperament: Peaceful
Colour Form: Ultra-bright toxic yellow branches with intense fluorescent glow, contrasting lighter axial tips and vivid neon tonalities throughout the corallites. Under heavy actinic lighting, the coral develops explosive radioactive yellow fluorescence with electric highlights and exceptional visual intensity. Under balanced white lighting, additional golden-yellow, lime and metallic citrus tones become visible across the colony.
Water Conditions: 24–26 °C, dKH 7.5–8.3, pH 8.0–8.4, sg 1.024–1.026
Family: Acroporidae
Lighting: High (PAR 250–450)
Water Flow: Strong, random and turbulent
Placement: Upper reef
Type: WYSIWYG Frag
🧬 Overview
The Acropora tenuis “Ultra Toxic Yellow” is an exceptionally vibrant SPS collector coral prized for its rare ultra-yellow coloration and intense actinic fluorescence. Highly sought after among tenuis collectors, this morph develops a glowing nuclear appearance that becomes dramatically radiant under modern reef LED systems.
Under strong blue-spectrum lighting, the coral produces vivid toxic-yellow fluorescence with electric neon intensity throughout the branch structure and corallites. In daylight-balanced systems, additional golden, citrus and lime-yellow tones emerge, creating remarkable depth and contrast rarely seen in SPS aquariums.
As the colony matures, it develops elegant compact branching growth, strong encrusting potential and highly textured corallites that create outstanding reef presence. In stable mature reef systems with high lighting and turbulent flow, Ultra Toxic Yellow tenuis rewards reef keepers with rapid growth, exceptional fluorescence and true high-end collector appeal.

📈 Optimal Parameters
Parameter | Ideal Range
Alkalinity (dKH) | 7.5–8.3
Calcium (Ca) | 400–450 ppm
Magnesium (Mg) | 1250–1400 ppm
Nitrate (NO₃) | 2–10 ppm
Phosphate (PO₄) | 0.02–0.08 ppm
📍 Placement
Place in the upper regions of the aquarium under strong stable lighting and powerful random flow to maximise fluorescence, colour saturation and compact branching growth.
