Behaviour & Temperament

Bumblebee Goby (Brackish) is a generally mild-mannered species (4/10), while Scarlet Badis is generally mild-mannered (3/10). This modest difference means Bumblebee Goby (Brackish) may occasionally assert dominance over Scarlet Badis.

Bumblebee Goby (Brackish) and Scarlet Badis both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks. Shrimp eaters may also prey on very small nano fish. Shrimp eaters may also prey on very small nano fish.

Water Parameters

The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 7 and 8.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 10–20 dGH. Regular testing will ensure conditions stay within this range.

Crucially, these species require different water types — one needs freshwater while the other requires brackish conditions. This is a hard barrier to keeping them together.

Tank Setup

To house Bumblebee Goby (Brackish) and Scarlet Badis together, plan for an aquarium of at least 46 litres with a minimum length of 45 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Sand (Sifters), Shells (Breeding/Hiding), Smooth Gravel (Sensitive Barbels), Plants - Densely covered, Plants - lighly covered. Meeting these requirements will help both species thrive.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Diet & Feeding

Feeding time deserves special attention with this pairing. Bumblebee Goby (Brackish) is a known shrimp eater and may prey on small invertebrates or nano fish like Scarlet Badis. Scarlet Badis is a known shrimp eater and may prey on small invertebrates or nano fish like Bumblebee Goby (Brackish).

Frequently Asked Questions

Can Bumblebee Goby (Brackish) and Scarlet Badis live together?

No. This combination is not recommended. Key incompatibilities — such as different water type needs — make cohabitation unsafe.

What size tank do Bumblebee Goby (Brackish) and Scarlet Badis need?

A minimum of 46 litres (tank length at least 45 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Bumblebee Goby (Brackish) and Scarlet Badis together?

Keep the aquarium between 24°C and 26°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.

Are Bumblebee Goby (Brackish) or Scarlet Badis aggressive?

Bumblebee Goby (Brackish) is generally mild-mannered (4/10) and Scarlet Badis is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Bumblebee Goby (Brackish) and Scarlet Badis need?

Both species overlap in the 7–8.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

How do I manage Bumblebee Goby (Brackish)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Bumblebee Goby (Brackish) space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
