Common name: Dragonets
The genus Callionymus, commonly known as Dragonets, is a fascinating group of small, vibrantly colored fish that inhabit the sandy and muddy bottoms of the Indo-Pacific region. These fish are renowned for their intricate patterns and striking hues, which make them a popular choice among saltwater aquarium enthusiasts. Dragonets are bottom dwellers and are often seen gliding gracefully over the substrate, using their large pectoral fins to maneuver.
One of the defining characteristics of Dragonets is their elongated bodies and the presence of a unique dorsal fin structure, which is often used in displays and courtship rituals. They are generally peaceful fish, but due to their specialized diet, they can be challenging to keep in captivity. Dragonets primarily feed on small invertebrates and copepods, and they require a well-established aquarium with a sufficient supply of live rock and a thriving population of microfauna.
In the aquarium, Dragonets are best kept in tanks with plenty of hiding spaces and a sandy substrate to mimic their natural habitat. They are not aggressive towards other species but can be territorial with their own kind, especially males. Therefore, it is advisable to keep only one male per tank unless the aquarium is large enough to accommodate multiple territories.
