Dragonets are a family of small, vibrantly colored saltwater fish. There are over 130 species of dragonets identified, a handful of which have been successfully kept by marine aquarists. Dragonets are somewhat similar in appearance to gobies. Their long, scale-less bodies are often vibrantly colored and adorned with intricate patterns. Although dragonets are considered as one of the most beautiful species of saltwater fish in the marine aquarium hobby, they are also one of the hardest to keep and require the care of an experienced hobbyist.
