    Product description

    Keep your nano tank at a rock-steady temperature without a bulky heater hogging your aquascape. The Hygger Mini Pro is a thumb-sized submersible heater built specifically for small tanks — perfect for bettas, shrimp, and nano community setups.

    The 10W model is rated for tanks up to 5 gallons, and the external controller lets you dial in the exact temperature without ever getting your hands wet.

    Why We Stock It

    • Super mini size — only about 4 inches long, easy to hide behind decor or plants
    • LED digital display — see real-time water temperature at a glance
    • External temperature controller — adjust the set temp without reaching into the tank
    • Adjustable range 59-93°F (15-34°C) — the ideal betta range of 78-80°F is easy to hold
    • Shatter-resistant quartz glass with a protective guard so fish can't scald themselves
    • Running-dry protection — shuts off automatically if the heater is exposed to air
    • Overheat protection — stops heating if water climbs above the safe range
    • Memory function — keeps your setting after a power outage
    • Freshwater and saltwater safe

    Setup Tips

    • Keep the heater fully submerged at all times — don't bury it in substrate
    • Mount it near your filter outflow so warm water circulates evenly
    • Keep the controller dry and away from splash zones
    • Unplug and let it cool before water changes

    Pairs perfectly with our live bettas and nano community fish. A stable temperature is one of the biggest factors in keeping tropical fish healthy — especially through the cooler months.
