The Bumblebee Goby (Brachygobius xanthomelas) is a very small, colourful goby species characterized by its' yellow body and dark brown patterns resembling that of a bumblebee.
While these goby species can thrive in brackish water, they can also thrive in freshwater provided that the water is hard.
These small, curious fish are an extremely entertaining addition to a nano-aquarium. These animals only reach approximately 1 inch in length and spend most of their time on the bottom of the aquarium. They should have access to very fine sand or gravel substrate, to allow them to dig and move comfortably. They do best in temperatures in the low 70's to low 80's range and live for 3 years on average.
A Bumblebee Goby can be comfortably housed in a 10 gallon (with many people having success with a 5-gallon setup), but keep in mind that these animals are extremely territorial. Extreme care should be applied when adding multiple fully-grown Bumblebee Goby to a single aquarium. It is recommended to only keep a single bumblebee goby per aquarium, or 8+ bumblebee goby to help disperse aggression. They should have lots of hiding places on the bottom of the aquarium to explore and defend. You may keep them with other small, peaceful fish, but most people have great success keeping them in a species-only aquarium.
These fish will not accept a flake, pellet, or freeze-dried diet and will require frozen or live prey such as bloodworms, daphnia, and baby brine shrimp.
