A great reef aquarium fish, best kept in groups. Scott W. Michael

[edit] Overview

An amiable, lovely fish that is not only beautiful and ­disease-resistant, but also engages in fascinating social behaviors when kept in groups. While shy when first added to the tank, this becomes a showy species, swimming about the water column, displaying at each other, and exhibiting typical zooplanktivore ­feeding behaviors.

Family: Ptereleotridae

Other common name(s):

  • Bar Goby
  • Chinese Zebra Goby

Native range:

Habitat: Reef-sand interface. Flat rocks with depressions dug underneath them provide excellent shelter sites.

Maximum length: 11 cm (4 in)

Minimum aquarium size: 76 L (20 gal)

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

General swimming level: All levels.

[edit] Feeding

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

[edit] Aquarium Compatibility

True to its name, it will dive into a hiding place when threatened. This is a happy-go-lucky species that gets along well with all of its tankmates, as long as they are not too large or belligerent. It also gets along well with its own kind and should be kept in pairs or small groups—they tend to acclimate more quickly and are more brazen when housed together. If harassed by more aggressive tankmates, this species will spend most of its time hiding and may eventually starve. It is an ideal species for a reef aquarium and not a threat to any ornamental invertebrates.

[edit] Special Care

This species is a proficient jumper—always keep the tank covered.

[edit] Breeding/Propagation

Demersal spawners that provide parental care to their broods.
