Can Leopard Bushfish (Ctenopoma) and Scarlet Badis Live Together?

Reviewed by Guidarium Editorial DeskUpdated April 28, 2026
Not Recommended

Leopard Bushfish (Ctenopoma) and Scarlet Badis are not recommended as tank mates due to piscivorous fish will prey on nano-sized tank mates.. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Leopard Bushfish (Ctenopoma) and Scarlet Badis?

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

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

Leopard Bushfish (Ctenopoma) and Scarlet Badis both frequent the Middle (Open Water) and 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.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

Worth noting: Leopard Bushfish (Ctenopoma) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

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 6.5 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 5–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Leopard Bushfish (Ctenopoma) and Scarlet Badis 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: Driftwood (Digestion/Hiding), Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater, Plants - lighly covered, Sand (Sifters). 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 Usually Fails in Practice

Leopard Bushfish (Ctenopoma) and Scarlet Badis are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Diet & Feeding

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

Frequently Asked Questions

Can Leopard Bushfish (Ctenopoma) and Scarlet Badis live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Leopard Bushfish (Ctenopoma) and Scarlet Badis 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 Leopard Bushfish (Ctenopoma) and Scarlet Badis 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 Leopard Bushfish (Ctenopoma) or Scarlet Badis aggressive?

Leopard Bushfish (Ctenopoma) 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 Leopard Bushfish (Ctenopoma) and Scarlet Badis 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.

How do I manage Scarlet Badis's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Scarlet Badis 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.

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.
