Brachygobius is a small genus of gobies. They are popular aquarium fish where a number of species are sold as bumblebee gobies because their colours are similar to those of bumblebees.[1]


Bumblebee gobies range in size from 1.5 cm to 4 cm.[2] They are generally coloured black with pale yellow to orange bands.[3] Males are generally slimmer than females and often have more vivid colours, typically orange rather than yellow.[3] Females may also have smaller and rounder heads.[2] When spawning, the colours of the males become deeper, the orange bands becoming red in the case of Brachygobius doriae.[2]


This genus is informally divided by taxonomists into the dwarf Brachygobius nunus-species group (e.g., B. nunus, B. aggregatus, and B. mekongensis) and the bigger Brachygobius doriae-species group (e.g., B. doriae, B. sabanus, and B. xanthomelas).[2]


There are currently nine recognized species in this genus:[4]


Bumblebee gobies are found across Southern and Southeast Asia primarily in freshwater habitats but also in slightly brackish waters.[2][3]


These gobies are oviparous. Eggs are deposited in a cave where they are guarded by the male.[3] Clutch size is around 150-200 eggs.[5] The eggs hatch after around seven days and the fry become free swimming another five to seven days later.[3]

In the aquarium[edit]

Bumblebee gobies are popular aquarium fish.[5] A tank around 40 liters in size will house a dozen specimens comfortably. Under good conditions they can live in an aquarium for around 5 years.[3] The most commonly traded species in the hobby belong to the Brachygobius doriae-species group but the smaller Brachygobius nunus is also traded occasionally.[2][3] Although many aquarium books use the name Brachygobius xanthozona, this species is very rare in the wild and is not commercially traded.[3]
