Blue Gudgeon Goby, Ptereleotris heteroptera, is a fish that does best in a well-established aquarium and is recommended to keep in groupings. With a maximum length at around five inches, its size makes it perfect for large and for small aquariums. Also known as the Blacktail Dartfish Goby, it is a "leaper" and requires a covered aquarium. Its body is a blue-grey that fluoresces under actinic lighting. Its tail is marked with a pronounced black spot. It is completely peaceful against other species and of members of its own family. If more than one is to be placed in the same aquarium, it is best to introduce them simultaneously and to allow plenty of space. Be sure to house it with compatible aquarium mates that will not be overly aggressive or confrontational to the Blue Gudgeon Goby.
