Bumblebees are not a good fish for the beginning aquarist although relatively hardy when given correct conditions. They require a small brackish tank (5 to 10 gallons) to themselves or with other small, slow, and peaceful fish that can tolerate mild brackish conditions. They will not likely feed on anything that is not alive or from the freezer (no flakes) and greatly enjoy bloodworms. They reach maximum size at around 1.5'' and tend to be relatively shy. Large, boisterous fish are not suitible as tankmates. Salinity should be kept at no lower than 1 teaspoon per gallon as freshwater raises the likelyhood of disease in this fish and promotes an early death. Like most gobies, these little guys have fused pectoral fins that create a suction cup ( they often cling to decorations and glass walls). If you are not sure about what this fish looks lke, run an image search on Google in its name. There are a number of subspecies with varying patterns and color but the pattern is generally black stripes on a yellow to bright orange body.
