Blue Face Koi Tang
The collector's grail — actual fish shown, 6 inches and thriving.
This listing is for the actual fish pictured and filmed: a collector-grade Blue Face Koi Tang, currently 6 inches. He has been in our thriving system for over 6 months, eats everything offered — pellets, nori, and frozen foods — and is well acclimated to tank life. Not aggressive and fully coral safe. A rare hybrid tang showing the koi pattern the hobby chases. Each specimen's pattern is completely unique, like a fingerprint — a true showpiece for a large display.

What it needs to thrive
- Lighting
- Any standard reef lighting — no special requirements.
- Flow
- Moderate reef flow with calm resting zones.
- Feeding
- Eating pellets, nori, and frozen foods. Herbivore first — keep nori daily and algae-based pellets in rotation.
- Temperament
- Not aggressive with tankmates; only territorial toward other tangs. Coral safe.
- Difficulty
- Intermediate
- Ideal Tank Size
- 125 gallons and up with long swimming runs.
- Water Parameters
- 76–80°F · salinity 1.024–1.026 SG · pH 8.1–8.4 · 0 ammonia / 0 nitrite · nitrate under 10 ppm
Plenty of open swimming room with established rockwork to graze. Strong flow appreciated.
Not aggressive in our system — peaceful toward tankmates. Semi-aggressive only with other tangs, especially fellow Zebrasoma. Fully coral safe.
Quarantine, dip, and acclimation
Quarantine
Hold all new fish in a bare-bottom 10–20 gallon QT for a minimum of 4 weeks. Observe for flashing, clamped fins, white spots, or breathing changes. Treat preventatively with copper (1.75–2.5 ppm chelated) or tank-transfer method for ich, plus a praziquantel course for flukes. Invertebrates and corals skip QT but go through dip and observation instead.
Recommended coral dip
For every new coral: a 5–10 minute bath in your reef-safe dip of choice (Bayer Complete, CoralRx, or Reef Primer) following label dosage, followed by two clean saltwater rinses. Inspect plugs and bases for flatworms, pyramid snails, and eggs — remove or refrag onto clean plugs before placing in display.
Acclimation
Float sealed bags in your QT or display for 15 minutes to match temperature. Then drip acclimate at 2–4 drops per second for 45–60 minutes until volume has tripled. Net livestock into the tank — never pour shipping water in. Dim the lights for the first 24 hours to reduce stress.
