Blue Gudgeon Goby (Ptereleotris heteroptera) Care
The Blue Gudgeon Goby, Ptereleptris heteroptera, is also known as the Blacktail Goby, and the Blue Gudgeon Dartfish. These fish come from the Indo-Pacific Ocean. They have a light blue-green body with a black spot on the center of the tail. These fish are notorious jumpers and should be kept in a tank with a lid.
Dartfish are carnivores and require a diet rich in both meaty foods, such as mysis and brine shrimp and finely chopped seafood.
The Blue Gudgeon Goby can grow to be about 5″ and can be housed in aquariums as small as 30 gallons with live rock, other non-aggressive fish, and a sand bed for hiding when threatened or sleeping at night. They should be kept singly or as a mated pair.
These fish are hardy, easy to care for, peaceful, and reef safe.
