As aquarium fish
Jumps out of open aquaria
This species is known to jump out of open aquaria.
Lives in a pair
This species can live as a pair (male and female).
This species is very shy and docile, so one should be careful when keeping it with more aggressive fish.
Over time this species can lose some of its colour when the food does not contain sufficient vitamins.
It pays therefore, to use a some type of enriched food, or one, specific to this species.
This species needs good hiding places, for example, between live rocks.
Family description (Microdesmidae)
Dartfish (Microdesmidae) are recognized by their unique torpedo like shape. All Dartfish need hiding places where they can withdraw to when feeling threatened. They do not normally naturally dig their own holes, but use ones made by other creatures.
They are generally a popular aquarium fish, relatively easy to keep, so for a small tank with peaceful fish the Dartfish is the obvious choice.
They can easily feel threatened by larger more aggressive fish with the result that they cannot feed enough and die by lack of food. One has therefore a greater chance of success when they are kept with smaller, peaceful, fish.
After first introducing a Dartfish, it is advizable to dim the light, so it can get used to the tank in peace.
|Distribution||Pacific Ocean: eastwards to the Tuamoto Islands, north to the Ryukyu Islands.|
