Dragon Goby Care Guide
Gobioides broussonnetii · Freshwater Fish

What Dragon Goby look like
Gobioides broussonnetii is a very elongate goby with small eyes, a broad mouth, fused pelvic fins, and long dorsal and anal fins that give it a ribbonlike silhouette. Healthy adults can develop a violet, silver, or blue-gray sheen. Pet-store juveniles are small, but the species can become a large bottom-dwelling fish that needs substantial floor space.
Behavior & temperament
Dragon Gobies are usually docile, nearly blind, and easily outcompeted by fast community fish. They are best kept in a brackish aquarium with fine sand or mudlike substrate, caves, gentle tank mates, and slow deliberate feeding. Freshwater-only setups and aggressive community tanks are common failure points. Conspecifics can be territorial unless the aquarium is very large.
Diet & feeding
Dragon Gobies are not aggressive predators despite their teeth. They sift and scrape algae, biofilm, detritus, tiny invertebrates, and fine food particles. In captivity, offer spirulina flakes, algae wafers, soft sinking foods, finely crushed prepared foods, brine shrimp, bloodworms, and other small meaty items that reach the substrate.
Behind the name
Gobioides means goby-like; broussonnetii honors French naturalist Pierre Marie Auguste Broussonet. Dragon Goby and Violet Goby are aquarium trade names.
