Ptereleotris zebra The Bar Goby is also referred to as the Zebra Barred Dartfish, Zebra Dart Goby, Zebra Goby, or Chinese Zebra Goby. Both the head and body of the Zebra Barred Dartfish are light green. Its attractive slender body has numerous vertical, evenly-spaced thin orange stripes displaying an intricate pattern. A tank of at least 30 gallons or larger with a sandy bottom, plants, and coral will provide a healthy environment for the bar goby. Small groups or pairs tend to do better in an aquarium than a single individual, but all need to be introduced to the tank simultaneously and have plenty of swimming room. The meaty diet of the Zebra Barred Dartfish should include fresh or frozen seafood and brine and mysid shrimp.
