Bumblebee Goby: tank size, group & compatibility data

Stocking notes

Small gobies with specialist feeding and water considerations; species identification matters.

For planning, StockingLab models Bumblebee Goby at its approximate adult size rather than the juvenile size commonly seen in shops. That matters because space use and waste production can change dramatically as fish mature.

What the calculator checks

• Whether the tank's usable volume is below the 45 L / 11.9 US gal reference minimum.
• Whether the selected group is below the planner's typical 6 fish social starting point.
• Whether target temperature and pH sit inside the planning range.
• Whether prospective tankmates create predation, fin-nipping, territorial or water-overlap conflicts.
• Whether too many fish accumulate in the same bottom swim zone.

Before buying

Use this profile as a shortlist tool, not as a substitute for a dedicated care source. Confirm adult size, diet, sex ratio, habitat structure and locally relevant water conditions before purchase.

How to interpret this Bumblebee Goby profile

At roughly 4 cm / 1.6 in adult length, Bumblebee Goby should be planned at mature size rather than the smaller size commonly offered for sale. The reference tank is 45+ L / 11.9+ US gal, with a planning water window of 23–28°C and pH 7–8.3. A midpoint around 25.5°C and pH 7.7 is useful only as a comparison aid; the aim is stable water that overlaps the needs of the whole community.

The 6+ social starting point means tank size should be judged for the group, not for a single shop-sized fish. Its modeled waste factor is relatively modest at 0.70×, but that does not make the 45 L reference tank optional: swimming room, social structure and oxygen demand are separate constraints. Activity is modeled at 0.55×, but lower activity should not be mistaken for permission to compress the fish into an undersized footprint.

Common planning mistakes to avoid

• Provide visual breaks and enough territory so one fish cannot control the whole footprint.
• Check that the planned temperature sits inside the shared 23–28°C range for every species in the community.
• Use the 45 L / 11.9 US gal reference as a starting point, then let actual tank dimensions, filtration and the full stock list refine the decision.

Bottom line: the profile is designed to screen a proposed aquarium for obvious pressure points. A result that passes StockingLab still needs to be checked against current, species-specific husbandry information for Brachygobius spp., especially diet, breeding behavior, sex ratio and habitat structure.
