The Bar Goby (Ptereleotris zebra), also known as the Zebra Barred Dartfish, is a peaceful, coral safe fish that can be kept with most other non-aggressive fish. They do best in small groups or as a pair, but should all be introduced at the same time. They need a 30+ gallon aquarium with a sandy bottom and ample rock work. Bar Gobies require a tight fitting lid as most Dartfish are prone to jumping. They should be fed a diet consisting of meaty foods like mysis, brine, LRS, & Rods, as well as pellets or flakes. Max size is around 4".
