How long do Mandarin Dragonets live?
Mandarin Dragonets can live 10 or more years in the right system — but many die within months in tanks without enough live food. A mature, pod-rich reef is the key.
What do Mandarin Dragonets eat?
They eat live copepods and amphipods almost exclusively; some individuals learn frozen foods, but most will not. The deadly mistake is assuming they'll take flake or pellets — they starve slowly; ensure a steady live-food supply or a refugium.
Tank size and water parameters
A 50-gallon (190 L) mature reef with a refugium suits one. Target 72-80°F (22-27°C), pH 8.1-8.4, specific gravity 1.020-1.025, ammonia/nitrite zero, nitrate low. Provide live rock and a deep sand bed hosting pods; keep one per tank (they fight).
Common mistakes with Mandarin Dragonets
Deadliest errors: putting them in a new or pod-poor tank (they starve); expecting them to eat prepared foods; multiple dragonets competing for food; and buying before the tank can support live prey.
Beginner mistakes to avoid
- Pod-poor tank — they starve without live copepods; use a refugium.
- Expecting prepared foods — most refuse flakes/pellets.
- Multiple dragonets — they fight over limited live food.
- New tank — only established, pod-rich reefs sustain them.
