Common name: Shoulderspot sandgoby

General information

The Violet Goby, also known as the Dragon Goby, is a unique and visually striking species that can add a touch of intrigue to any brackish or marine aquarium. Despite its fierce appearance, with a serpentine body and dragon-like jaws, Fusigobius humeralis is a peaceful and shy fish that often hides during the day.

This species is not commonly found in the aquarium trade, but it can be a fascinating addition for hobbyists looking to diversify their tank inhabitants. It's important to note that while they have sharp teeth, these are primarily used for sifting through sand to find food, not for aggression.

Care

Violet Gobies require a tank with plenty of hiding spots and a sandy substrate that they can sift through for food. They are not demanding in terms of water conditions but do prefer a slightly brackish environment. A varied diet of live and frozen foods such as brine shrimp, bloodworms, and small crustaceans will keep them healthy and well-nourished.

Due to their potential size, reaching up to 24 inches in length, a larger aquarium is necessary to accommodate their growth. They are generally peaceful and can be kept with other non-aggressive brackish water fish.

Reproduction

Breeding Violet Gobies in captivity is challenging and not often successful. In the wild, they spawn in burrows, where the male guards the eggs until they hatch. In an aquarium setting, replicating their natural breeding conditions can be difficult.

Habitat

Fusigobius humeralis is found in brackish estuaries and coastal waters, often burrowing in sandy or muddy substrates. They are native to the western Atlantic, ranging from the southern United States down to Brazil, including the Gulf of Mexico and the Caribbean Sea.
