Clown Knife Fish (Chitala ornata) for Sale in Canada

The Clown Knife Fish (Chitala ornata) is one of the most recognizable and fascinating freshwater predator fish in the aquarium hobby.

Native to Southeast Asia, the Clown Knife Fish is admired by experienced aquarists for its unique appearance and unusual method of movement. Its long anal fin allows it to swim smoothly both forward and backward, creating an elegant, almost ghost-like motion through the water.

How Large Does a Clown Knife Fish Get?

Clown Knife Fish can potentially reach approximately 30–40 inches (75–100 cm) under excellent long-term conditions, although size in home aquariums may vary.

Even before reaching maximum size, they become large fish requiring a substantial aquarium.

Plan for the Adult Fish

Before purchasing, ensure you have a realistic plan for:

• A very large aquarium
• Extensive swimming length
• Adequate aquarium width
• Excellent filtration
• Regular water changes
• Strong biological filtration
• Appropriately sized tank mates
• Long-term care

This species can outgrow conventional home aquariums.

Aquarium Size

A large aquarium is essential. Juveniles can begin in a smaller grow-out aquarium, but long-term housing for an adult requires a very large system.

A minimum of approximately 180 gallons may be considered for a juvenile or developing specimen, while a fully grown adult requires a substantially larger custom-built aquarium.

Prioritize Length and Width

The ideal aquarium should provide:

• Exceptional length
• Generous width
• Open swimming areas
• Secure hiding places
• Large smooth driftwood
• Caves or sheltered areas
• Excellent filtration
• Stable water quality
• Secure aquarium lid

Avoid cramped conditions and narrow tanks that restrict turning space.

Feeding Your Clown Knife Fish

A Carnivorous Freshwater Predator

Clown Knife Fish require a varied diet of high-quality, appropriately sized foods.

Recommended Foods

• High-quality predator pellets, where accepted
• Frozen shrimp
• Krill
• Prawns
• Mussels
• Earthworms
• Fish-based prepared foods
• Other suitable aquatic protein foods

Juvenile fish may initially be more selective when adapting to prepared foods.

Important Feeding Advice

Avoid relying on live feeder fish as a staple diet. Feeder fish can introduce parasites and disease and may not provide balanced nutrition.

Avoid mammal or poultry meat as a regular food source.

Feed appropriately sized portions and avoid overfeeding.

Behaviour and Temperament

Graceful but Predatory

Clown Knife Fish can appear peaceful during the day, especially when resting in sheltered areas, but they are predators.

They may:

• Hide during daylight hours
• Become more active in low light
• Hunt smaller fish
• Swallow tank mates that fit in their mouth
• Display individual territorial behaviour
• Become more confident with time

Young Clown Knife Fish can be shy and may require time to settle into a new aquarium.

Providing secure hiding places can help reduce stress.

Compatible Tank Mates

Choose Tank Mates Carefully

Any fish small enough to fit into the Clown Knife’s mouth may eventually become prey.

Potential tank mates in a sufficiently large aquarium may include appropriately sized:

• Large peaceful cichlids
• Large catfish
• Silver Dollars
• Large barbs
• Other robust fish with compatible water requirements

Avoid

• Small tetras
• Small barbs
• Small catfish
• Shrimp
• Small community fish
• Any fish small enough to be swallowed

Compatibility depends heavily on aquarium size and individual temperament.

Creating the Ideal Clown Knife Aquarium

Combine Open Water With Secure Hiding Places

A good setup should provide both swimming space and security.

Recommended Features

• Large smooth driftwood
• Spacious caves
• Sheltered areas
• Dimmer sections of the aquarium
• Open swimming lanes
• Smooth décor
• Strong filtration
• Stable water conditions

Avoid sharp decorations that could injure the fish’s long body.

Clown Knife Fish Care for Juveniles

Give Young Fish Time to Settle

Young Clown Knife Fish may initially be shy.

To help them adjust:

• Provide secure hiding places
• Keep lighting moderate
• Avoid frequent disturbances
• Maintain stable water conditions
• Offer food consistently
• Gradually introduce suitable prepared foods

As they become accustomed to their environment, many individuals become increasingly confident.
