General information on Engineer Goby
The Engineer Goby (pholidichthys leucotaenia) belongs to a distinct family from gobies and the blennies. The markings on it change throughout its existence. The predominant colors are black to dark blue on white. In the beginning, the markings are horizontal and run across the body. As they grow older, they transform into vertical bands. It is best to keep it in an aquarium that has the bottom covered with sand so that it can build burrows. It requires a peaceful tankmate and lots of places to hide. Smaller groups or pairs tend to thrive in aquariums, however, they require that they be introduced concurrently in the tank. Engineer Goby has been known to successfully spawn in an aquarium.
