The Blue Gudgeon Dartfish, commonly referred to as the Blacktail Goby or Blacktail Dartfish, originates from the reefs of Fiji. They have an elongated body, which is pale blue or green in color with a prominent black spot on their tail. They enjoy being in pairs, and make a wonderful fish for a fish only or reef aquarium.
It 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 feeds mostly on prey suspended in the water column, but will pick food off the substrate as well. The Blue Gudgeon Dartfish feeds on a diet which includes mysis shrimp, brine shrimp, table shrimp, and frozen food preparations for carnivores. It should be fed at least three times per day.

My two Blue Gudgeon Gobies are exquisitely beautiful and extremely shy, so the occasional glimpse of them swimming is special treat. They spend most of their time hiding under a rock with just their bright iridescent blue eyes and tiny faces visible. Often they "snuggle" alongside my Firefish and Yellow Watchman Gobies, forming an amusing, appealing row of tiny faces peeking out. Temperamentally, they are much like my Firefish. They only come out when they think the coast is clear, then swim with their long pencil-thin blue bodies loosely intertwined. I recommend them to anyone who especially loves Gobies or who enjoys watching the daily dramas that take place in hidden lower areas of a reef aquarium. My two rely on each other for courage, so I suspect they might feel more confident in a small school.
