Threadfin Goldie Anthias
Living orange flame in open water — the reef's signature schooling fish.
The classic lyretail anthias: females in brilliant orange, males shifting to magenta with an elongated dorsal filament. Kept in a group over open rockwork they recreate the look of a wild reef slope better than any other fish. They need frequent feeding — three small meals a day is the difference between thriving and fading.

What it needs to thrive
- Lighting
- Any standard reef lighting — no special requirements.
- Flow
- Moderate reef flow with calm resting zones.
- Feeding
- Small meaty foods 3× daily — enriched mysis, calanus, and pellets. Automated feeding helps enormously.
- Temperament
- Peaceful and reef safe; mild squabbling within the harem.
- Difficulty
- Intermediate
- Ideal Tank Size
- 70 gallons and up for a small group.
- Water Parameters
- 76–80°F · salinity 1.024–1.026 SG · pH 8.1–8.4 · 0 ammonia / 0 nitrite · nitrate under 10 ppm
Open water above and around the rockwork, in a group with one male to several females.
Peaceful and reef safe. The dominant female will convert to male, so keep only one male per group.
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.
