Can Bumblebee Goby (Brackish) and Congo Tetra Live Together?
Bumblebee Goby (Brackish) and Congo Tetra are not recommended as tank mates due to incompatible water types. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle Bumblebee Goby (Brackish) and Congo Tetra?
Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament
Bumblebee Goby (Brackish) is a generally mild-mannered species (4/10), while Congo Tetra is peaceful (2/10). This modest difference means Bumblebee Goby (Brackish) may occasionally assert dominance over Congo Tetra.
In terms of spatial distribution, Bumblebee Goby (Brackish) prefers the Bottom (Substrate) zone, whereas Congo Tetra occupies the Middle (Open Water) and Top (Surface) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.
Worth noting: Congo Tetra is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.
Both fish can tolerate a pH between 7 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 10–18 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 Congo Tetra together, plan for an aquarium of at least 110 litres with a minimum length of 90 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.
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 - Floating. 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.

Frequently Asked Questions
Can Bumblebee Goby (Brackish) and Congo Tetra 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 Congo Tetra need?
A minimum of 110 litres (tank length at least 90 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 Congo Tetra together?
Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.
Are Bumblebee Goby (Brackish) or Congo Tetra aggressive?
Bumblebee Goby (Brackish) is generally mild-mannered (4/10) and Congo Tetra is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Bumblebee Goby (Brackish) and Congo Tetra need?
Both species overlap in the 7–7.5 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.
