Engineer Goby (Pholidichthys leucotaenia)

The Engineer Goby, also known as the Convict Blenny, is a fascinating and highly unique fish that brings movement and mystery to your aquarium. Juveniles resemble eels with bold black-and-white stripes, while adults transition into a more muted pattern with a striking head-to-tail gradient. Known for their industrious digging behavior, Engineer Gobies create elaborate tunnel systems beneath your aquascape, often working in pairs or small groups.

Tank Requirements

Engineer Gobies do best in aquariums of 55 gallons or more with deep sand beds and stable rockwork. Their burrowing nature means aquascaping should be secure, as they may shift sand and base rocks while digging. A tight-fitting lid is also recommended, as they may jump when startled or during nighttime activity.

Quiet Diggers, Active Architects

These peaceful and hardy fish are ideal for both beginner and experienced reef-keepers. Engineer Gobies spend much of their time rearranging substrate and creating hiding places, which adds natural behavior and intrigue to your tank. They rarely bother tankmates and are generally shy, venturing out more frequently at feeding time or in low lighting.

Diet and Feeding

Engineer Gobies are carnivorous and benefit from a varied diet of meaty foods such as mysis shrimp, brine shrimp, finely chopped seafood, and high-quality pellets or frozen fare. Feed once or twice daily to ensure healthy growth and long-term vitality.

Tankmates and Behavior

Engineer Gobies are peaceful and reef-safe, posing no threat to corals or most invertebrates. Their digging may occasionally disturb sand-sifting or bottom-dwelling species, so it's best to pair them with mid-to-upper swimmers or other non-burrowing community fish. When kept singly or in bonded pairs, they thrive without territorial issues.
