🔹 Black Hole Chernobyl Catalaphyllia
Catalaphyllia jardinei (L Size – Ultra Rare Morph)
🔹 Quick Stats
Care Level: Moderate to Advanced
Temperament: Semi-aggressive (long sweeper tentacles; allow wide spacing)
Colour Form: A breathtaking ultra morph, featuring deep black undertones across the tentacles fused with toxic neon green and radioactive yellow highlights, creating a cosmic “black hole” glow effect. Under actinic and blue-dominant lighting, the fluorescence reaches extreme intensity, making it one of the most radiant and rare Catalaphyllia varieties.
Water Conditions: 24–27 °C, dKH 8–12, pH 8.0–8.4, sg 1.024–1.026
Family: Caryophylliidae
Lighting: Low to moderate (enhances fluorescence while avoiding tissue stress)
Supplements: Calcium, Magnesium, Trace Elements, Amino Acids
Water Flow: Gentle to moderate — maintains natural tentacle sweep without damage
Placement: Lower reef levels with room for full tentacle extension
🧬 Overview
The Black Hole Chernobyl Catalaphyllia is an ultra-rare collector’s piece, combining dark cosmic tones with radioactive fluorescence. Its long, flowing tentacles shimmer in black, neon green, and toxic yellow, producing a surreal “outer space” effect. A coral of this caliber is a true centerpiece specimen, reserved for advanced collectors seeking the rarest morphs worldwide.
🍽️ Feeding & Care
Although photosynthetic, this coral thrives with supplemental feeding. Target-feed with mysis shrimp, chopped seafood, or enriched brine 2–3 times weekly. Feeding enhances tissue inflation, deepens fluorescent coloration, and accelerates growth.
📈 Optimal Parameters
-
Alkalinity (dKH): 8–12
-
Calcium (Ca): 420–460 ppm
-
Magnesium (Mg): 1250–1350 ppm
-
Nitrate (NO₃): 2–10 ppm
-
Phosphate (PO₄): 0.02–0.08 ppm
📍 Placement
Best positioned on the sand bed or lower rock structures in low to moderate flow. Ensure open space to accommodate long, sweeping tentacles. Under actinic lighting, the “black hole” effect becomes fully visible, with glowing toxic tones contrasting the dark base for a truly ultra effect.
