Size Offered: Approximately 3 Inches

This listing is for a juvenile Sumatran Tigerfish measuring approximately 3 inches.

Young Datnoids can change significantly as they grow. Colouration and stripe intensity may vary depending on genetics, stress level, lighting, diet, aquarium conditions, and individual development.

Fish size is approximate and natural variation should be expected.

How Large Does Datnoides microlepis Get?

The Sumatran Tigerfish can become a large freshwater predator.

Experienced keepers should plan for an adult potentially reaching approximately 18 inches (45 cm) or more under favourable conditions.

Plan for the Adult Fish

Do not select an aquarium based only on the fish’s current 3-inch size.

Before purchasing, plan for:

• A large long-term aquarium
• Strong biological filtration
• Excellent mechanical filtration
• Sufficient swimming space
• Appropriate large tank mates if attempted
• A long-term commitment to water changes and maintenance

A juvenile Tigerfish can grow into a substantial centerpiece fish.

Aquarium Size

A large aquarium is essential for long-term care. While a 3-inch juvenile can temporarily be housed in a smaller grow-out aquarium, adult housing should be planned well in advance.

For a single adult, an aquarium of approximately 180 gallons or larger should be considered, with larger systems preferred for multiple Datnoids or tank mates.

Recommended Aquarium Setup

• Large mature aquarium
• Powerful biological filtration
• Strong mechanical filtration
• Excellent oxygenation
• Moderate water movement
• Open swimming space
• Large driftwood
• Secure rocks
• Smooth décor
• Dark or natural substrate
• Secure lid

A spacious aquarium with stable water conditions is essential for long-term success.

Feeding Your Sumatran Tigerfish

Sumatran Tigerfish are carnivorous predators and should receive a varied diet of high-quality foods.

Suitable Foods

• High-quality carnivore pellets
• Frozen shrimp
• Prawns
• Mussels
• Clams
• Krill
• Other appropriately sized frozen aquatic foods
• Quality fish-based prepared foods

A varied diet can support healthy growth and overall condition.

Feeding Tips

Some newly imported or young Tigerfish may initially be reluctant to accept prepared foods. Patience and a gradual transition can help encourage feeding.

Avoid making live feeder fish a regular part of the diet because they may introduce parasites and disease.

Behaviour and Temperament

A Predatory Freshwater Fish

Sumatran Tigerfish have a strong predatory instinct. Any fish small enough to fit inside their mouths may eventually become prey.

As they grow, tank-mate selection becomes increasingly important.

Tank Mate Considerations

In a sufficiently large aquarium, experienced keepers may consider robust fish that are too large to swallow and have compatible water requirements.

Potential compatibility depends on:

• Individual temperament
• Aquarium size
• Adult size of every fish
• Feeding behaviour
• Available swimming space

Avoid:

• Small fish
• Slow-moving prey-sized fish
• Delicate species
• Fish that can fit inside the Tigerfish’s mouth

Compatibility can never be guaranteed.

---

Keeping Multiple Sumatran Tigerfish

Multiple Tigerfish may sometimes be kept together in a very large aquarium, but this requires careful planning.

Important Considerations

• Provide enormous swimming space
• Avoid overcrowding
• Choose fish of compatible sizes
• Provide powerful filtration
• Monitor aggression
• Feed a balanced diet
• Have a backup aquarium if separation becomes necessary

As with many predatory fish, individual temperament can vary significantly.

---

Supporting Strong Colour and Stripe Definition

The appearance of a Sumatran Tigerfish can be influenced by its environment and overall condition.

Colour-Care Tips

• Maintain excellent water quality
• Feed a varied, nutritious diet
• Reduce unnecessary stress
• Provide suitable lighting
• Avoid overcrowding
• Provide sufficient swimming space
• Use natural décor and dark backgrounds if desired

Stripe colour and body tone may naturally change throughout the day and under different environmental conditions.
