Bumblebee Goby

Bumblebee Goby key facts

Care level

Intermediate

Lifespan

3-5 years

Size

2.5-4cm

Temperature

22〜28℃

Diet

Live and frozen foods such as Artemia and Daphnia

Tank

A 45 x 30cm base, about 41 litres, is the practical minimum. Provide plenty of cover to break lines of sight so weaker fish can escape attention, and use gentle filtration such as an air-powered sponge unit.

Water Temperature & Quality

Seriously Fish gives 22-28C, pH 7.0-8.5 and 8-20dGH. Crushed coral in the substrate buffers the water, or marine salt can be added at about 2 grams per litre. FishBase records pH 8.0, 9-19dH and 22-29C in the wild.

Tank Mates

Not an ideal community fish; a species-only tank is best. Males are territorial, so buying six or more spreads the aggression, and the fish are bolder and behave more naturally in numbers.

Diet & Feeding

Small live foods such as Artemia and Daphnia should be considered essential. Some individuals learn to take frozen alternatives, but dried products are normally ignored.

Breeding & Spawning

A cave spawner. Small flower pots, ceramic tubes or shells serve as sites. The female leaves after spawning and the male guards the 100-200 eggs, which hatch in 7-9 days. Fry need microscopic foods such as Paramecium or Brachionus.

Health & Notes

The trade name covers several species, and misidentification as B. nunus or B. xanthozonus, or confusion with the similar B. sabanus, is common. Fish sold under the same name may not share the same water requirements.

About Bumblebee Goby

A tiny 2.5-4cm freshwater goby with bold yellow-and-black bands. Prefers hard, mineral-rich to slightly brackish water and rarely eats dry food, making it a species suited to intermediate keepers.

7 things to know before welcoming a Bumblebee Goby

1. 1Small Body, Big Attitude

   Despite reaching only 2.5 to 4 cm, Bumblebee Gobies are territorial and will defend a small patch of space. When keeping several together or with similarly shaped fish, provide plenty of hiding spots and visual breaks in the layout to help them settle.

2. 2Hard Water to Slightly Brackish

   Bumblebee Gobies prefer hard, mineral-rich freshwater to slightly brackish conditions. They're sensitive to sudden water changes, so take extra time during acclimation and avoid abrupt shifts in water parameters.

3. 3Live and Frozen Food Are a Must

   This species rarely accepts dry food, so live or frozen foods such as brine shrimp and daphnia are essential. Some individuals do learn to take frozen food, but you should settle how you will source food before bringing them home.

4. 4Best Suited for Intermediate Keepers

   Because of the specific water chemistry and feeding requirements, this species is considered suitable for intermediate aquarists. Having some prior freshwater fishkeeping experience makes day-to-day care much smoother.

5. 5Best Kept in a Single-Species Tank

   Because they are territorial, they are not well suited to community tanks, and a single-species setup is the standard approach. Males squabble with each other, so introducing a group of six or more spreads out the aggression and helps them settle and show natural behavior.

6. 6The Signature Yellow-and-Black Bands

   The bold contrast of yellow and black bands is this fish's biggest visual draw, standing out clearly against tank decor. Watching them dart along the substrate is a constant source of entertainment.

7. 7Prepare the Tank Before You Bring Them Home

   Set up plenty of hiding spots that break lines of sight, and get water parameters stable in advance to reduce stress at introduction. Plan for a single-species tank, with a footprint of about 45 x 30 cm (roughly 41 L) as a guide.

Frequently asked questions about Bumblebee Goby

Q.Can they be trained to eat flake food?

A.Some individuals may occasionally accept it, but this shouldn't be relied upon. It's safer to plan on live foods like brine shrimp or frozen alternatives as their staple diet.

Q.Do they need brackish water to thrive?

A.They can be kept in hard freshwater. Aim for 22-28°C, pH 7.0-8.5 and 8-20 dGH, and maintain hardness by mixing coral sand into the substrate or adding about 2 g of marine salt per liter. Adjust water conditions gradually rather than all at once.

Q.Can multiple Bumblebee Gobies be kept together?

A.Males contest territory, so a group of six or more is recommended to spread out the aggression. Use a tank of about 45 x 30 cm (roughly 41 L) and provide plenty of hiding spots that break lines of sight so weaker fish can escape.

Q.Can they live with other fish species?

A.They are not well suited to community tanks, and a single-species tank is the standard approach. Because they are strongly territorial, keeping them with other fish is not recommended.

Q.Is this species suitable for beginners?

A.Because of the specific water chemistry needs and feeding requirements, it's considered better suited to intermediate keepers. Gaining some general freshwater fishkeeping experience first is recommended before taking one on.
