Scissortail Goby (Asia Pacific)
The Scissortail goby is unique among the dart fishes for having tall dorsal and anal fins giving it a stunning silhouette. Its front half is dusty blue and its rear a deep velvety navy to black. Sparkling blue is visible on its face when the light hits it just right. Its tail is square but appears to be a lyre shape as the center is transparent to yellowish. They are an impressive fish on their own but look even better in a group of at least three individuals, although we find six or more to be incredibly impressive. It schools well with other dart fishes as well. Males and females are visually identical. It grows up to 5.5 inches; we recommend an aquarium 40 gallons or larger.
Dart gobies are extremely peaceful and do best with other mild-mannered fish. When threatened many dart gobies, with the exception of firefish, may quickly dive under the sand for cover. The firefish prefers to hide within the rockwork. A fine sand bed of at least two inches, but preferably deeper, will offer a safe refuge. Flat rocks placed on the sand will further help in creating a natural environment. We recommend the tank be securely covered as gobies may be prone to jumping from open top aquaria. It is normal for them to be quite shy when initially introduced, however once settled in they prefer to spend time in the open.
Gobies are primarily carnivores and their diet should include plenty of high quality meaty items, marine algae, Spirulina, and frozen Mysis shrimp. It is preferable to feed at least twice a day and to let some food land on the bottom of the aquarium if the dart goby has not yet earned to eat from the water column. Frozen food is best, however in time they may learn to eat dry foods.
As one of the largest families of fish there are near countless varieties of gobies which inhabit every different niche on the reef. They are coral safe and typically quite active and friendly with other fish. They have the ability to change sex to form pairs, although they don't always do so. Most gobies are imported from the Philippines.
Gobies are diminutive fish typically with elongated bodies, and as such we do not recommend any aggressive or large-mouthed fish to be kept with them; this includes all groupers, snappers, sweetlips, soapfish, lionfish, eels, goatfish, anglers/frogfish, leaf fish, etc.
