The Quanlong Mini USB aquarium heater keeps small tanks at a stable, comfortable temperature without the fuss of a full-size heater. Its slim submersible body fits pico and desktop tanks — like the Pico EcoFlaura — without taking up space or getting in the way of the view.

Good to know:
– USB-powered — runs from a wall adapter or power bank
– Compact submersible design for small and nano tanks
– Adjustable temperature control for a stable reading
– Suitable for freshwater and saltwater setups
– Built-in protection against overheating
