[edit] Overview

This newly described deep-water goby looks very much like a dartfish with great appeal to many reef aquarists. It is not uncommon, but enters the aquarium trade only on occasion. Like a dartfish, it hovers over the substrate and disappears into a hole when threatened.

Family: Gobiidae

Other common name(s):

  • Tiny Dartfish

Native range:

Habitat: In the wild, this species may found in small groups hovering above the substrate.

Maximum length: 5 cm (2 in)

Minimum aquarium size: 19 L (5 gal)

Water: Marine 24 °C (297 K, 75 °F) - 28 °C (301 K, 82 °F)

[edit] Feeding

Meaty foods, including finely shredded frozen seafood, mysid shrimp, frozen preparations, pigment-enriched flake food, and Cyclop-eeze (a preferred food for this fish). Feed at least twice a day.

[edit] Aquarium Compatibility

Keep this species singly, in pairs, or in groups if your tank is of moderate size. Do not house with aggressive fishes or with tankmates that can swallow it whole. If pestered, it will hide and not feed.

[edit] Notes

Firefishes may harass it in smaller tanks. Although not as likely to jump out of an open tank as a firefish, it is best to keep the tank covered.
