Native to the shallow lagoons, coastal reefs, under-ledges and coral heads in the Indian Ocean. Colors and markings on this fish varies with age. As a juvenile, the body is a dark blue with horizontal markings, running the length of the body. An adult either becomes black or white, with vertical banding or is darkly marbled. Juveniles swim in tight formations, trying to mimic the look of a venomous catfish to scare away would-be predators. This fish is actually a dartfish, not a goby. Gobies and dartfish share the same family, which is why dartfish are more often listed under "Gobies." Known also by the names of Engineer or Convict Blenny and Convict Worm or Pacific Neon Goby.

Adaptation: Best as a mated pair or in a small group as long as they are all introduced at the same time. Needs plenty of room to swim and pl;aces to hide. A burrower, this fish needs a sand bottom with rock-work, preferably live rock and live sand. It will dig extensive tunnels under the rock-work, stirring up detritus build-up at the same time. Fairly disease-resistant, it can withstand less then optimal water conditions, though NEVER recommended.
Compatibility: The larger sized fish may eat tiny fish and ornamental shrimp. Best with peaceful tank-mates.
