Can Banjo Catfish and Black Skirt Tetra Live Together?

Possible with Caution

Keeping Banjo Catfish and Black Skirt Tetra together is possible but requires caution due to potential behavioral clashes. Provide a spacious tank of at least 60 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Banjo Catfish and Black Skirt 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

Banjo Catfish is a peaceful species (1/10), while Black Skirt Tetra is generally mild-mannered (4/10). This modest difference means Black Skirt Tetra may occasionally assert dominance over Banjo Catfish.

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

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Banjo Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat. Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.

Water Parameters

The safe temperature window for both species falls between 20°C and 26°C. Aim for the midpoint of this range (around 23.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 3–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Banjo Catfish and Black Skirt Tetra together, plan for an aquarium of at least 60 litres with a minimum length of 60 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Sand (Sifters), Leaf Litter/Blackwater, Plants - Densely 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.

Why This Pairing Needs Extra Planning in Practice

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Banjo Catfish and Black Skirt Tetra need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

Frequently Asked Questions

Can Banjo Catfish and Black Skirt Tetra live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 60 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Banjo Catfish and Black Skirt Tetra need?

A minimum of 60 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 Banjo Catfish and Black Skirt Tetra together?

Keep the aquarium between 20°C and 26°C. A target of around 23.0°C sits comfortably within both species' preferred ranges.

Are Banjo Catfish or Black Skirt Tetra aggressive?

Banjo Catfish is peaceful (1/10) and Black Skirt Tetra is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Banjo Catfish and Black Skirt Tetra need?

Both species overlap in the 6–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Black Skirt Tetra nip Banjo Catfish's fins?

Black Skirt Tetra is a known fin nipper. If Banjo Catfish 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.

Does Banjo Catfish being nocturnal affect compatibility?

Banjo Catfish is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Banjo Catfish during evening hours.
