Behaviour & Temperament

Black Skirt Tetra is a generally mild-mannered species (4/10), while Neon Blue Goby is generally mild-mannered (3/10). This modest difference means Black Skirt Tetra may occasionally assert dominance over Neon Blue Goby.

In terms of spatial distribution, Black Skirt Tetra prefers the Middle (Open Water) zone, whereas Neon Blue Goby occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Water Parameters

The safe temperature window for both species falls between 22°C and 26°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 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 4–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Black Skirt Tetra and Neon Blue Goby together, plan for an aquarium of at least 69 litres with a minimum length of 60 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: Plants - Densely covered, Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels), Sand (Sifters). Meeting these requirements will help both species thrive.

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

Frequently Asked Questions

Can Black Skirt Tetra and Neon Blue Goby live together?

Yes. Black Skirt Tetra and Neon Blue Goby are considered ideal tank mates. Their water parameters, temperaments, and behaviour profiles are well matched for a community aquarium.

What size tank do Black Skirt Tetra and Neon Blue Goby need?

A minimum of 69 litres (tank length at least 60 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 Black Skirt Tetra and Neon Blue Goby together?

Keep the aquarium between 22°C and 26°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.

Are Black Skirt Tetra or Neon Blue Goby aggressive?

Black Skirt Tetra is generally mild-mannered (4/10) and Neon Blue Goby is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Black Skirt Tetra and Neon Blue Goby need?

Both species overlap in the 6.5–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Black Skirt Tetra nip Neon Blue Goby's fins?

Black Skirt Tetra is a known fin nipper. If Neon Blue Goby has long or flowing fins, there is a real risk of fin damage. Keeping Black Skirt Tetra in a larger group can help redirect nipping behaviour toward conspecifics.

How do I manage Neon Blue Goby's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Neon Blue Goby 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.
