Scissortail Dartfish

A peaceful, eyecatching species, especially when kept in groups. Scott W. Michael


Here is an unusual and likable addition to the peaceful community tank that will spend its time hovering in the open and darting about the aquarium. It is a good candidate to be kept in a small school.

Family: Ptereleotridae

Other common name(s):

  • Blackfin Dartfish
  • Scissortail Goby

Native range:

Habitat: Reef-sand interface, lagoons and bays. In the aquarium, they will use flat rocks with depressions dug underneath as shelter sites.

Maximum length: 14 cm (6 in)

Minimum aquarium size: 76 L (20 gal)

Water: Marine 24 °C (75 °F) - 28 °C (82 °F)

General swimming level: Mid-level.


Carnivore. Feed meaty foods, such as mysid shrimp and enriched adult brine shrimp, at least twice a day.

Aquarium Compatibility

When first added to the tank, the Scissortail Dartfish invariably goes into hiding. As it becomes comfortable with its new surroundings, it will begin swimming about in the water ­column.

Special Care

It is a proficient jumper that readily leaps from open aquariums. The tank must absolutely be kept tightly covered at all times.


This fish is very amiable and rarely, if ever, bothers other fish species. It may occasionally display toward and briefly chase other dartfishes, but rarely harms them. If picked on by large or aggressively competitive tankmates, it will hide incessantly, will not eat, and will eventually perish. More than one can and should be housed in the same tank, as they tend to do better when in groups. It will not harm ornamental invertebrates.
