🐟 Black Ruby Barb ( Puntius nigrofasciatus )

It doesn’t just school — it strikes.

The Black Ruby Barb doesn’t swim through a tank
 it cuts through it. Deep charcoal blacks, molten ruby reds, and that sharp metallic sheen give this fish a look that feels forged, not grown. When the school turns, the upper body flashes like a line of hot coals — a moving ember crown that demands attention.

Males sharpen even harder with age, throwing deeper reds and tighter formation, turning every pass across the glass into a coordinated display of heat and motion.

This isn’t your everyday barb. At Uncle Joe’s Fish Shed, we raise them right here in Florida or bring them in tiny, hand‑selected batches from trusted local breeders who match our standards. No mass‑runs. No color‑washed imports. Just limited, boutique‑quality fish chosen for strength, saturation, and attitude.

Limited runs only — because real quality isn’t produced. It’s curated.
