Difficulty of Care: 8/10
The bumblebee goby (B. xanthozona) is a small, bottom-dwelling, carnivorous fish that is distinguished by its solid, unbroken black stripes and bright yellow body.
Tank and Water Requirements
Minimum Tank Size: 10 gallons for two gobies
Water Temperature: 73–85 °F (23–30 °C)
Water pH: 7–8.5
Water Hardness: 12–18dH
Bumblebee gobies are highly territorial among their own species, and overstocking will result in a tremendous amount of quarreling and possibly injury. To ensure the best living conditions, only stock two gobies in a ten-gallon aquarium. Numbers can be increased with aquariums that have larger footprints.
Sand is the proper substrate for bumblebee gobies, as it will allow them to move freely and burrow on occasion. Driftwood, river rocks, and live plants are also recommended to replicate natural conditions and to provide hiding.
 
Feeding
Here is where the "difficulty of care" rating takes on an 8 out of 10 score. Bumblebee gobies are tricky to feed. Because they are an opportunistic-style feeder, they will snap at anything that might swim or float by, so flakes and dry foods are out of the question.
Live food is really the best option for bumblebee gobies.
They will readily take tubifex and blood worms that are still living. They will eat frozen ones if there is a slight current to keep the food moving around.
Hatched brine shrimp are also a great option. The same current needs apply for frozen brine shrimp.
In my experience with my gobies, I found that tiny, live Convict Cichlid fry were the perfect meal for a hungry goby.
Keep in mind that if the food doesn't move, your gobies won't eat it.
