[ARRIVED 28-JAN-2026] ORCA 50W Heater

Description

ORCA Aquarium Heater – 50W

Compact fully submersible aquarium heater designed for nano tanks and smaller tropical aquariums

Quick Facts

  • Power: 50W
  • Type: Fully submersible aquarium heater
  • Best For: Nano and small aquariums
  • Control: Adjustable temperature dial
  • Safety: Automatic shut-off protection
  • Indicator: LED operating light

Is this for you?

✔️ Good if:

  • You run a nano or small tropical aquarium
  • You keep shrimp, bettas, or nano fish
  • You want stable water temperature in smaller tanks
  • You need a compact heater for limited space

❌ Avoid if:

  • You have a medium or large aquarium
  • You need heavy heating in cold environments
  • You plan to expose the heater above water level
  • You want a heater without temperature monitoring

Why this heater?

The ORCA 50W Heater is designed for smaller aquariums where stable temperature matters but space is limited.

Smaller tanks fluctuate faster than larger aquariums, making consistent heating especially important for shrimp, bettas, nano fish, and planted setups.

With adjustable settings, automatic shut-off, and compact sizing, this heater provides a practical solution for nano aquarium stability.

Common mistakes

  • Using an undersized heater in cold rooms
  • Powering on before fully submerging
  • Installing in dead spots with poor water movement
  • Skipping thermometer checks
  • Using in tanks larger than recommended

Use made simple

  • Fully submerge before powering on
  • Install vertically or horizontally
  • Adjust desired temperature
  • Allow time for heating stabilisation
  • Use alongside a thermometer for confirmation

Pair with

  • Digital aquarium thermometer
  • Nano sponge filter or internal filter
  • Bettas and shrimp tanks
  • Planted nano aquariums
  • Temperature controller (optional)
NTA Insight:
Small tanks change temperature faster than larger aquariums. A correctly sized heater matters more in nano tanks because there is less water volume buffering temperature swings.

    Live Arrival & Ordering FAQ

    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.
