Bumblebee Goby (Brackish)

Brachygobius xanthozonus

Gobies & Gudgeons

A miniature, bottom-dwelling goby famous for its striking black and yellow stripes. While they are often sold as freshwater fish and can survive in it temporarily, they are highly susceptible to fungal infections in fresh water and truly require a brackish setup (SG 1.002-1.005) to thrive long-term. They are notoriously picky eaters, often ignoring flakes in favor of live or frozen foods (like bloodworms or brine shrimp).

Standard

The standard form found in the aquarium trade. Best kept in species-only brackish setups or with very peaceful, similarly-sized brackish tank mates. Males will establish tiny territories in empty snail shells or crevices and fiercely defend them from other males.

Bumblebee Goby (Brackish) Care Guide Summary

The Bumblebee Goby (Brackish), scientifically known as Brachygobius xanthozonus, belongs to the Gobies & Gudgeons family group. Adults reach a maximum size of approximately 4.5 cm and have a depressed body shape with a slow growth rate. Classified as mostly peaceful, this species primarily occupies the bottom zone of the aquarium and produces a low level of biological waste.

To thrive, the Bumblebee Goby (Brackish) requires a brackish required aquarium with a minimum volume of 38 litres and a tank length of at least 45 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 78.5 and a general hardness of 1025 dGH. A low water flow is preferred. An aquarium test kit can help you monitor these values.

Due to its specialist needs, the Bumblebee Goby (Brackish) is best suited for fishkeepers who can provide a carefully planned setup. The Bumblebee Goby (Brackish) is typically available in one standard form.

Bumblebee Goby (Brackish) Habitat Setup

When setting up an aquarium for the Bumblebee Goby (Brackish), a low water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour, smooth gravel or rounded substrate to protect their sensitive barbels, and shells for breeding and shelter. Browse aquarium sand substrate options to find the best fit.

Bumblebee Goby (Brackish) Compatibility Notes

Classified as mostly peaceful, the Bumblebee Goby (Brackish) is a social species that requires the company of its own kind to thrive. When choosing tankmates, ornamental shrimp are not safe companions, conspecific aggression can be intense, especially in smaller tanks, and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.

Similar Species

Banded Archerfish (Brackish)

Toxotes jaculatrix

Oddballs
25 cm Semi-Aggressive

Famous for their ability to shoot down insects with a precise jet of water. As surface-dwelling predators native to mangrove estuaries, they require hard, brackish water to thrive long-term. They have a high prey drive and will eat any fish small enough to fit in their mouths. A tight-fitting lid is absolutely mandatory as they are exceptional jumpers.

Figure 8 Puffer (Brackish)

Dichotomyctere ocellatus

Puffers
8 cm Aggressive

A small, highly intelligent, and interactive pufferfish known for the distinctive figure-eight pattern on its back. While often sold as freshwater fish, they strictly require a low-end brackish environment (Specific Gravity 1.005-1.008) for long-term health and a full lifespan. They are aggressive fin-nippers and strict carnivores that require hard-shelled foods (like snails) to keep their continuously growing teeth trimmed.

Neon Blue Goby

Stiphodon atropurpureus

Gobies & Gudgeons
5 cm Mostly Peaceful

A stunning, specialized freshwater goby native to fast-flowing hill streams in Asia. Males display brilliant neon blue metallic coloration, while females are striped. They are specialized biofilm grazers ('Aufwuchs' eaters) and require mature tanks with established algae/biofilm stones. They are obligate stream dwellers requiring high oxygen and strong flow.

Scarlet Badis

Dario dario

Other
2 cm Mostly Peaceful

One of the smallest known aquarium fish, resembling a tiny jewel. Males display brilliant vertical red and iridescent blue stripes. While beautiful, they are known for being extremely picky eaters, often refusing dry foods and requiring live or frozen micro-foods (Daphnia, Baby Brine Shrimp). Males act like tiny Cichlids and will stake out territories.

Amazon Puffer

Colomesus asellus

Puffers
8 cm Mostly Peaceful

One of the few truly freshwater, community-safe pufferfish. Native to the Amazon basin, these energetic swimmers are known for their bumblebee-like stripes and erratic swimming patterns. Unlike most puffers, they are social and prefer to be kept in groups. CRITICAL WARNING: This species has the fastest-growing teeth of any puffer. They REQUIRE a daily diet of hard-shelled foods (snails, clams, crustaceans) or they will require manual dentistry (trimming) to prevent starvation.

Knight Goby

Stigmatogobius sadanundio

Gobies & Gudgeons
9 cm Semi-Aggressive

A distinct, high-bodied goby found in estuaries across South Asia. Unlike most bottom-dwelling gobies, the Knight Goby frequently hovers in the water column. While often sold as freshwater fish, they thrive best in slightly brackish water (SG 1.003-1.005) or very hard, alkaline freshwater. They are territorial and notorious fin-nippers, making them poor tankmates for Guppies or Bettas.
