Diet

Difficulty Level
This species is challenging for most hobbyists due to its specialized dietary requirements—it depends almost entirely on live copepods and amphipods and rarely accepts prepared foods. Success requires an established, mature aquarium with substantial live sand and rock supporting a robust copepod population, stable water conditions, and close observation to ensure adequate nutrition.
Diet Details
The Spotted Dragonet is a microphagous carnivore that feeds primarily on small benthic crustaceans, particularly copepods and amphipods. In captivity, it requires a well-established, mature aquarium with abundant live sand and rubble where copepod populations can thrive; supplemental feeding with small frozen foods may be necessary but live prey is strongly preferred.
Temperament
Peaceful
Min tank size
30 gallons
Common Health Issues
Starvation (inadequate copepod populations), parasitic infections, bacterial infections from poor water quality
