Flag‑tail prochilodus (Semaprochilodus insignis)
These fish are straight‑up energy: silver body, big lips, and that red‑and‑black flag‑striped tail whipping around like they own the place. They’re the perfect “movement fish” for big displays — always cruising, always working, always showing off.
🔥 What Makes a Flagtail a Flagtail
Silver chrome body that stays clean and reflective
Bold red/black flagtail pattern — the whole reason people buy them
Constant motion — they don’t sit still, ever
Great with larger peaceful fish (cichlids, rainbows, geos, etc.)
Zero fear, zero shyness — they settle fast and take over the midwater lane
