Why choose the L340 Mega Clown Pleco?

The L340 Mega Clown Pleco is one of the most attractive members of the Hypancistrus group. Its body is covered in bold cream and black markings that form intricate maze-like patterns, making every individual fish completely unique.

Unlike larger Plecos, the L340 remains compact, making it suitable for medium-sized aquariums while still delivering the striking appearance collectors look for in premium L-number species.

Primarily nocturnal, these Plecos spend the day sheltering beneath driftwood and inside caves before emerging after lights out to forage for protein-rich foods.

Benefits

  • Rare collector's L-number Pleco
  • Beautiful maze-like black and cream pattern
  • Compact adult size
  • Ideal feature fish for planted aquariums
  • Peaceful with community fish
  • Long-lived with proper care

Care made simple

  • Temperature: 27–30Β°C
  • pH: 6.0–7.5
  • Diet: High-quality carnivore pellets, frozen bloodworms, blackworms, brine shrimp, mysis shrimp and occasional seafood
  • Water: Very clean, highly oxygenated and well-filtered
  • Setup: Multiple caves, driftwood, rockwork and moderate water movement
  • Perform regular water changes to maintain pristine water quality.

Pairs perfectly with

  • Corydoras
  • Rainbowfish
  • Peaceful Apistogramma
  • Larger Tetras
  • Small to medium community fish
NTA Insight:
The L340 is often mistaken for other "Clown" Plecos, but experienced collectors know just how special this species is. Its striking maze-like markings become even more impressive as it matures. Unlike algae-eating Bristlenose, the L340 is primarily a carnivorous Pleco, so quality protein-rich foods are essential for maintaining colour, growth and long-term health.

FAQ

Does the L340 eat algae?

Only incidentally. The L340 is primarily a carnivorous Pleco and should be fed high-quality sinking carnivore foods along with frozen foods such as bloodworms, mysis shrimp and blackworms.

How large does the L340 Mega Clown Pleco grow?

Most adults reach around 8–10 cm, making them considerably smaller than many other L-number Plecos and suitable for medium-sized aquariums.

Can I keep more than one L340?

Yes, but only if the aquarium provides multiple caves and territories. Adult males can become territorial, particularly during breeding.

Do they need caves?

Absolutely. Like most Hypancistrus, they spend much of the day inside caves or beneath driftwood. Providing multiple hiding places helps reduce stress and encourages natural behaviour.

Are they suitable for beginners?

The L340 is best suited to aquarists with some experience. Stable water quality, excellent filtration and a protein-rich diet are the keys to successfully keeping this beautiful collector's Pleco.

    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.
