Keeping your underwater buddies cozy just got easier with the DaToo MINI 25W Aquarium Heater. Seriously, it's the tiniest heater out there—perfect for those snug 1 to 6 gallon tanks. It's like having a personal thermostat for your fish, locking in that sweet spot of 78°F, which bettas and most tropical fish absolutely love. And because it's so compact (we're talking just 0.2 inches long), it'll fit anywhere. Plus, with its rubber sealing and quartz glass build, it's tough enough to handle whatever your aquarium throws at it.

Now, let's talk features—because this little gadget packs a punch. First off, it keeps the temperature steady at 78°F without you lifting a finger. It's the smallest 25W heater you'll find, making it a no-brainer for small tanks. Safety? Covered, thanks to that rubber sealing layer and the explosion-proof, crack-proof quartz glass. And because we know you like to keep an eye on things, it comes with a free sticker thermometer. Handy, right?

Just a heads-up: this heater needs to stay underwater while it's doing its thing. Oh, and it plays nice with both glass and acrylic tanks—so no worries there.
