Can Black Skirt Tetra and Leopard Bushfish (Ctenopoma) Live Together?

🟡Possible with Caution

Keeping Black Skirt Tetra and Leopard Bushfish (Ctenopoma) together is possible but requires caution due to potential behavioral clashes. Provide a spacious tank of at least 132 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Behaviour & Temperament

Both Black Skirt Tetra and Leopard Bushfish (Ctenopoma) are generally mild-mannered species with an aggression score of 4/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Black Skirt Tetra and Leopard Bushfish (Ctenopoma) both frequent the Middle (Open Water) 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Leopard Bushfish (Ctenopoma) 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 23°C and 26°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.

Both fish can tolerate a pH between 6 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 5–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Black Skirt Tetra and Leopard Bushfish (Ctenopoma) together, plan for an aquarium of at least 132 litres with a minimum length of 90 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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: Plants - Densely covered, Driftwood (Digestion/Hiding), Plants - Floating, Leaf Litter/Blackwater. 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 Leopard Bushfish (Ctenopoma) live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 132 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Black Skirt Tetra and Leopard Bushfish (Ctenopoma) need?

A minimum of 132 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 Black Skirt Tetra and Leopard Bushfish (Ctenopoma) together?

Keep the aquarium between 23°C and 26°C. A target of around 24.5°C sits comfortably within both species' preferred ranges.

Are Black Skirt Tetra or Leopard Bushfish (Ctenopoma) aggressive?

Black Skirt Tetra is generally mild-mannered (4/10) and Leopard Bushfish (Ctenopoma) is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Black Skirt Tetra and Leopard Bushfish (Ctenopoma) need?

Both species overlap in the 6–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Black Skirt Tetra nip Leopard Bushfish (Ctenopoma)'s fins?

Black Skirt Tetra is a known fin nipper. If Leopard Bushfish (Ctenopoma) 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 Leopard Bushfish (Ctenopoma) being nocturnal affect compatibility?

Leopard Bushfish (Ctenopoma) 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 Leopard Bushfish (Ctenopoma) during evening hours.
