The Blue Gudgeon Goby, commonly referred to as the Blacktail Goby or Spottail Dartfish, originates from the reefs of the Indo-Pacific. It has an elongated body, which is pale blue or green in color with a prominent black spot on the tail.

The Blue Gudgeon Goby should be housed in a 30 gallon or larger aquarium with plenty of loose coral rubble, and requires ample swimming room with a sand bottom for burrowing. It may try to jump out of the aquarium or other small opening, so a tight-fitting lid is required. Rarely will it become aggressive towards other fish. It enjoys being part of a group or in a mated pair, and makes a wonderful addition to a fish-only or reef aquarium.

The Blue Gudgeon Goby feeds mostly on prey suspended in the water column, but will pick food off the substrate as well. The diet should include mysid shrimp, brine shrimp, table shrimp, and frozen food preparations for carnivores. It should be fed at least three times per day.
