Description

Tiger Bichir (Polypterus endlicherii)

Powerful, prehistoric and unmistakably impressive, the Tiger Bichir is a large African predator recognised by its broad head, armoured body and bold saddle-like markings. Its ancient appearance and deliberate hunting behaviour make it an extraordinary feature fish for experienced aquarists with suitably large aquariums.

Is this for you?

✔️ Perfect if:

  • You want a dramatic prehistoric-looking feature fish.
  • You have a very large aquarium with substantial floor space.
  • You can provide a secure, tightly fitted aquarium lid.
  • You understand that any fish small enough to swallow may be treated as food.

❌ Avoid if:

  • You have a small or medium-sized community aquarium.

  • You cannot accommodate its considerable adult size.
  • Your aquarium has openings through which the fish could escape.

Why choose a Tiger Bichir?

The Tiger Bichir is one of the most impressive members of the ancient Polypteridae family. Its heavy body, broad flattened head and bold vertical saddles create an appearance that looks more like a prehistoric reptile than a conventional aquarium fish.

Bichirs possess a modified swim bladder that functions much like a lung, allowing them to rise to the surface and breathe atmospheric air. Watching a Tiger Bichir patrol the aquarium floor before surfacing for air is one of the behaviours that makes this species so fascinating.

Although generally slow-moving and not needlessly aggressive, the Tiger Bichir is an opportunistic predator. Tank mates must be robust, peaceful and far too large to fit inside its mouth. Its eventual adult size must be carefully considered before purchase.

Benefits

  • Striking prehistoric appearance
  • Bold tiger-like saddle markings
  • Fascinating air-breathing behaviour
  • Intelligent and responsive at feeding time
  • Long-lived when properly maintained
  • Outstanding centrepiece for a large predator aquarium

Care made simple

  • Temperature: 24–28°C
  • pH: 6.5–7.8
  • Diet: Carnivorous sinking pellets, prawns, mussels, earthworms, fish flesh and suitable frozen foods
  • Water: Clean, stable and well filtered with moderate circulation
  • Substrate: Fine sand or smooth gravel to protect the underside of the fish
  • Setup: Large footprint, open floor space, sturdy driftwood and secure shaded shelters
  • Use a tightly fitted and weighted lid, as Bichirs are powerful escape artists.
  • Always maintain access to the water's surface so the fish can breathe atmospheric air.
  • Avoid feeding mammalian or poultry meat, which is poorly suited to its digestive system.

Pairs perfectly with

  • Large peaceful Severums
  • Adult Silver Dollars
  • Large Synodontis Catfish
  • Oscar Cichlids of compatible temperament
  • Other similarly sized Bichirs
NTA Insight:
The Tiger Bichir is frequently sold as a manageable juvenile, but its eventual adult size is substantial. Aquarium length and floor area matter more than height because this species spends most of its time along the bottom. Plan for the adult fish from the beginning and never assume that tank mates are safe simply because they appear too large to eat—the Tiger Bichir has a surprisingly wide mouth.

FAQ

How large does a Tiger Bichir grow?

Tiger Bichirs can reach approximately 60–75 cm as adults. Their large eventual size means they require a substantial aquarium with generous floor space and strong filtration.

Is the Tiger Bichir aggressive?

It is generally calm toward fish it cannot consume, but it is a natural predator. Small and slender tank mates may be hunted, particularly after the aquarium lights are turned off.

Can it live with small fish?

No. Any fish that can fit inside the Bichir's mouth should be considered potential prey. Tank mates must be large-bodied, robust and compatible in temperament.

Does a Tiger Bichir need to breathe air?

Yes. Bichirs possess a specialised respiratory organ that allows them to breathe atmospheric air. The aquarium must always provide unobstructed access to the surface.

Why does the aquarium need a secure lid?

Bichirs are powerful escape artists that can push through surprisingly small openings. A tightly fitted, weighted lid should cover all gaps around filters, cables and plumbing.

Can multiple Bichirs be kept together?

Yes, similarly sized Bichirs can often coexist when the aquarium is sufficiently large and offers multiple shelters. Avoid combining individuals with a major size difference, as the smaller fish may be attacked or swallowed.

What should I feed a Tiger Bichir?

Offer a varied carnivorous diet consisting of quality sinking predator pellets, prawns, mussels, earthworms and suitable frozen fish foods. Feeder fish are unnecessary and may introduce parasites or disease.

How long do Tiger Bichirs live?

With a suitably large aquarium, excellent water quality and balanced nutrition, Tiger Bichirs may live for 15–20 years or longer.

    Live Arrival & Ordering FAQ

    Why do livestock prices sometimes change?

    Unlike manufactured products, fish and shrimp continue to grow and develop over time. Their value changes as they increase in size, develop colour, or become breeding pairs.

    Our prices are based on the current size, quality and availability of each specimen. While pricing often remains stable for around 3–4 months, it may be updated at any time to reflect these changes.

    We always aim to offer healthy, high-quality livestock at fair and competitive prices.

    Do you offer a live arrival guarantee?

    Yes. All livestock is covered by our Live Arrival Guarantee.

    In the rare event of DOA, please contact us promptly with clear photos of the livestock in the original unopened bag.

    Please review our full DOA and store policies before purchase.

    Can you ship to all states in Australia?

    No. Due to state restrictions, we cannot ship livestock or live plants to WA and TAS.

    What should I check before ordering?

    Before placing an order, make sure:

    • Your tank is fully cycled and stable
    • Your aquarium has enough space for the species
    • Your current livestock are compatible in temperament, size, and requirements
    • Your water parameters, habitat, and temperature suit the species
    • You are not adding too many fish at once
    What should I expect when my fish arrives?

    It is normal for fish, shrimp, or snails to look pale, stressed, or less active after shipping.

    This is temporary. Most livestock will settle and regain colour within a few days.

    How long does it take for fish to settle in?

    Most livestock will take 3–7 days to fully adjust to their new environment.

    Should I feed my fish immediately after arrival?

    No. We recommend waiting 24 hours before feeding to allow them to settle.

    If you already have fish in your tank, feeding them before introducing new arrivals can help reduce stress.

    Why do fish sometimes struggle after being added to a tank?

    In most cases, issues are caused by tank conditions, not shipping.

    • Uncycled or unstable tanks
    • Poor water parameters
    • Overstocking
    • Unsuitable tank mates
    What is Nano Tanks Australia’s main tip for new livestock?

    Most livestock losses happen in immature or unstable tanks, not during shipping.

    If your setup is not fully established, the risk to new arrivals is significantly higher.

    Not sure if this fish is right for your setup?

    If you are unsure whether this species suits your setup, contact us before ordering and we’ll help point you in the right direction.
