TSN x RTC Catfish (Pseudoplatystoma fasciatum × Phractocephalus hemioliopterus) for Sale in Canada

The TSN x RTC Catfish is an extraordinary hybrid monster fish created from the Tiger Shovelnose Catfish and the Redtail Catfish. Combining characteristics associated with both famous South American catfish, this hybrid is highly sought after by experienced monster fish keepers looking for a powerful, fast-growing, and visually impressive centerpiece fish.

The TSN x RTC Catfish may display a mixture of characteristics from both parent species. Its appearance can include an elongated body, broad head, long barbels, bold patterning, and distinctive coloration. Because this is a hybrid, the exact appearance, growth pattern, and adult characteristics can vary between individual fish.

This is a fish for serious monster aquarium keepers only. TSN x RTC Catfish can grow extremely large and require enormous long-term housing, powerful filtration, and careful planning before purchase. A small aquarium may temporarily house a juvenile, but buyers must have a realistic plan for the fish’s eventual size.

Monster Aquarium Canada offers TSN x RTC Catfish for experienced aquarium hobbyists in Canada.

• Impressive elongated body shape
• Long sensory barbels

Understanding the Parent Species

Tiger Shovelnose Catfish Influence

The Tiger Shovelnose lineage can contribute:

• Long, streamlined body shape
• Attractive vertical or irregular patterning
• Long barbels
• Active swimming behaviour
• Strong predatory instincts

Redtail Catfish Influence

The Redtail Catfish lineage may contribute:

• Broad head and mouth
• Powerful body
• Fast growth
• Strong feeding response
• Dark body coloration
• Contrasting tail and fin coloration

Because the TSN x RTC is a hybrid, individual fish may show these traits in different proportions.

How Large Does a TSN x RTC Catfish Get?

This hybrid has the potential to become an extremely large fish.

Adult size can vary significantly because hybrids do not always grow or develop exactly like either parent species. However, keepers should plan for a fish that may reach well over 3 feet (90 cm) and potentially require substantially more space.

Important Long-Term Commitment

Do not purchase a TSN x RTC Catfish based only on its juvenile size.

Before buying, ensure you have a realistic long-term plan for:

• An extremely large aquarium
• An indoor pond or custom system
• Industrial-strength filtration
• Large-volume water changes
• Safe transportation equipment
• Long-term feeding costs
• Emergency backup plans

This fish can outgrow conventional home aquariums.

Aquarium and Housing Requirements

A juvenile TSN x RTC can begin life in a large aquarium, but permanent housing must be planned around its enormous potential adult size.

Recommended Long-Term Housing

For a large adult, a custom aquarium or indoor pond measured in hundreds or potentially thousands of gallons may be required. The exact size should depend on the individual fish’s adult dimensions, activity level, and body width.

Prioritize floor space, turning room, and swimming length, rather than simply choosing a tall aquarium.

Essential Equipment

• Extremely powerful biological filtration
• Heavy-duty mechanical filtration
• Strong circulation
• Excellent oxygenation
• Large water volume
• Reliable heaters where required
• Secure covers
• Large drains or efficient water-change systems
• Protected aquarium equipment

Planning ahead is essential because large monster fish produce substantial biological waste.

Feeding Your TSN x RTC Catfish

TSN x RTC Catfish are opportunistic predators with large appetites. Their diet should change as they grow.

Suitable Foods

• High-quality sinking carnivore pellets
• Quality catfish pellets
• Shrimp
• Mussels
• Clams
• Fish-based prepared foods
• Other appropriately sized frozen aquatic foods

A varied diet can help provide balanced nutrition.

Important Feeding Advice

Avoid relying on live feeder fish as a routine food source. Feeder fish can introduce parasites and disease and may provide poor nutritional balance.

Also avoid feeding mammal or bird meats, such as beef heart or chicken, as staple foods. These are not natural long-term foods for large predatory freshwater catfish.

Feed according to the fish’s size, condition, age, and activity level. Juveniles may require more frequent feeding than large adults.

Behaviour and Temperament

A Powerful Predatory Catfish

TSN x RTC Catfish should be considered a predatory monster fish. Any tank mate small enough to fit inside its mouth may eventually become prey.

As the fish grows, compatibility with other aquarium fish becomes increasingly difficult.

Possible Tank Mate Considerations

Only exceptionally large, robust fish in an appropriately enormous system may be considered by highly experienced keepers. Even then, compatibility is never guaranteed.

Avoid:

• Small fish
• Medium-sized fish that can eventually fit in its mouth
• Small catfish
• Slow-moving fish
• Delicate species
• Valuable fish that could be injured or swallowed

Never assume a current tank mate will remain safe as the TSN x RTC grows.

---

Growth Rate

TSN x RTC Catfish can grow rapidly when young. Growth rate depends on:

• Genetics
• Diet
• Water quality
• Aquarium volume
• Temperature
• Overall health

Fast growth should never be encouraged through excessive feeding. Overfeeding can damage water quality and contribute to health problems.

The best approach is providing excellent water conditions, adequate space, and a balanced diet.

---

Ideal Monster Fish Setup

A dedicated large predator aquarium or custom freshwater system is the best option.

Recommended Setup Features

• Massive open swimming area
• Smooth substrate or bare bottom for easy maintenance
• Minimal sharp décor
• Securely positioned large driftwood
• Powerful filtration
• High oxygen levels
• Easy access for large water changes

As the fish grows, aquarium décor should never restrict its ability to turn comfortably.
