Mandarin and Dragonet Fish
Mandarin Fish or Dragonets have to be one of the most beautiful Marine Aquarium fish you could keep. With the exception of diet they are quite hardy too, being resistand to many Marine Aquarium diseases. The issue can be getting them to feed. They tend to prefer live food as in Copepods and Brine Shrimp. They will take frozen food too. But it might be a bit of trial and error.
