Scissortail Dartfish

The Scissortail Dartfish, or Blackfin Goby, is a graceful and active fish with a slender, elongated body. It is a soft grey-blue toward the head that transitions into a darker charcoal-to-black toward its deeply forked "scissortail." They are very social and are almost always seen swimming in pairs or small groups in the open water column, darting back to their shared burrow at the sign of a threat. They are much more active than Firefish and bring a lot of movement to the mid-water levels of the tank. They are peaceful, hardy, and reef-safe, making them an excellent choice for a community reef.
