Aqueon Mini Flat Submersible Heater 10W for 2.5–5 Gallon Aquariums

Compact warmth that fits small tanks

The Aqueon Mini Heater provides steady warmth for tropical fish in compact spaces. Specifically designed for desktop aquariums from 2.5 to 5 gallons, its 10 watt output is purposefully sized to maintain a comfortable environment without overpowering the tank’s profile. The flat, low‑profile design blends with décor while keeping your fish in clear view as you watch them glide through a reliably warm habitat.

Built to endure daily use, this heater features a shatterproof housing and a fully submersible body. Its flexible orientation—install it vertically or horizontally—lets you tailor placement to the tank’s dimensions and your cabinet or stand setup, ensuring even temperature distribution across the water column.

Smart safety and versatile compatibility

A thermal safety shut‑off helps protect against overheating, offering peace of mind in busy homes or classrooms. The unit is compatible with both acrylic and glass aquariums, so you can mix and match tank materials without needing a different heater.
