Introduction to the Unique Engineer Goby:

The Engineer Goby, scientific name Pholidichthys leucotaenia, is an unassuming, but fascinating, fish species which is native to the Western Pacific Ocean. Although its saltwater habitat may seem bright and distant, this small, hardy fish is as close as your local pet store. This saltwater fish may be tiny—the adult variety of Engineer Goby typically grows to maximum lengths of only two inches—but what it lacks in size, it makes up for in personality.

Physical Characteristics of the Engineer Goby

The Engineer Goby can be distinguished from other fish species by its unique physical characteristics. It has a light tan body, with a white or yellow hue which tapers off towards the tail. The dorsal fin is noticeably long, extending along the back. The Engineer Goby has three anteriorly-oriented vertical stripes; two black stripes on either side of a prominent, central yellow stripe. The eyes of the Engineer Goby are also notable, being larger than typical for its species; this is thought to increase its visual acuity, and thus its ability to assess its environment.

Life Habits of the Engineer Goby

The Engineer Goby thrives in the company of other fish species. It is often found in groups of five to eight individuals. In its native saltwater habitats, it inhabits areas of rocky substrate where it can form tunnels and crevices. Burrowing is an important part of the life cycle of the Engineer Goby, as it requires such a space in order to court and mate. In addition to creating these tunnels, the Engineer Goby is also known to eat algae and small invertebrates, as well as smaller snails and crustaceans.

The Social Nature of the Engineer Goby

The Engineer Goby is a fascinating species, and its social habits create a unique viewing experience for its captors. It is not uncommon for the species to congregate around the same rock or coral, and weave intricate paths and tunnels as it burrows and forages for food. This makes aquariums which contain the Engineer Goby an excellent choice for those interested in observing the social behaviors of this species.


The Engineer Goby is a small, but fascinating, saltwater fish species that easily captivates the attention of the average aquarium hobbyists. It is unique among other species due to its prominently striped colors, relatively large eyes, and impressive social habits.
