DaToo Mini Aquarium Heater 25W – Perfect for Small Betta Fish Tanks, Automatically Maintains 78°F

💧 Ideal for Small Tanks
DaToo has designed this heater specifically for small aquariums, from 1 to 5 gallons. At only 0.2 inches in thickness, it’s incredibly compact, maximizing space for your fish to swim freely. Even in the tiniest tanks, it fits seamlessly, providing effective heating without taking up valuable space.

🔋 Energy Efficient Heating
Thanks to its automatic on/off system, this heater only operates when necessary, making it energy efficient. When the water reaches the desired temperature, the heater switches off to conserve energy, turning back on only when needed. This makes it an eco-friendly choice for any fish enthusiast.

🔧 Durable & Safe Construction
Safety is a top priority with the DaToo Mini Aquarium Heater. Unlike traditional heaters, this one uses a rubber sealing layer to prevent leaks and ensure maximum electrical safety. The quartz glass construction is both explosion-proof and crack-resistant, so you never have to worry about it breaking down.

💡 Simple & Reliable Operation
This heater’s no-setup design takes the hassle out of temperature control. There’s no complicated adjustment process – simply plug it in, and it will maintain the perfect temperature. The built-in light indicator makes monitoring easy – a red light means it’s heating, and a green light means the desired temperature has been reached.

🛡️ Enhanced Safety Features
With a quartz glass exterior and advanced rubber sealing, the DaToo Mini Heater is built to last. It’s explosion-proof and shatter-resistant, providing peace of mind for aquarium owners. Plus, the fully submersible design ensures it works safely under water at all times.

🐠 Perfect for Betta & Tropical Fish
Bettas and tropical fish thrive in warmer water environments. The DaToo Heater keeps the water at an optimal 78°F, which is ideal for these species. It’s particularly effective for fish keepers who want to maintain a consistent environment without constantly checking or adjusting the heater.

🌍 Compact & Discreet Design
Measuring just 0.2 inches thick, this is the smallest 25W heater available. Its minimalist design means it’s almost invisible in your tank, so it won’t detract from the beauty of your aquarium setup while keeping your fish safe and warm. Whether you have a 1-gallon or 5-gallon tank, it blends in effortlessly.
