Review: 78 degrees constant - My betta is warm and happy (all the time) - I like this heater for my Biorb 4 gallon tank (for my betta) it keeps the tank 78 constant - so perfect - never had a problem, it's small and it works. It's made in Italy of all places. Just follow the directions. Don't turn it on until it's immersed in water. That's it. It works. My betta is perfectly warm and happy in his own Biorb tank. I know some of the reviews are not so great - but I followed the directions (immerse first, then turn on) and never had a problem, it works!!! P.S. I did have one day - heat wave here in CA where the ambient temp in the house was almost 90 and the tank was at the top of the safe zone - so I unplugged the heater that day and plugged it back in the morning. It was fine. I will have to see how it goes in the summer - but we will have the AC during those heat waves (hopefully). So I would caution if you do see your in house temps rising to keep eye on it - and in that case it's easy just unplug! It only went down a few degrees that night - still in the safe zone but I didn't want my betta to cook! Review: Unexpected - Have been using Aqueon preset heaters for years. Have never made a negative review before. Purchased it and discovered it’s not preset or able to be set . It depends on the filter flow and room temperature. Yes it’s possible to find the correct balance. But if something changed. It could do permanent damage to the fish. Very sorry. Will understand if you don’t wish to post it. ## Features - Perfect size heater for Aqeuon Mini Bows and other small aquariums - Ideal for desktop fish tank aquariums up to 5 gallons - Features thermal safety shut-off - Aquarium heater is shatterproof ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.2 out of 5 stars 540 Reviews | ## Images ![Aqueon Fish Tank Mini Heater, 10-watt, Plastic - Image 1](https://m.media-amazon.com/images/I/818WAQjp2vL.jpg) ![Aqueon Fish Tank Mini Heater, 10-watt, Plastic - Image 2](https://m.media-amazon.com/images/I/81RRcoDD1aL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 78 degrees constant - My betta is warm and happy (all the time) *by A***N on May 14, 2015* I like this heater for my Biorb 4 gallon tank (for my betta) it keeps the tank 78 constant - so perfect - never had a problem, it's small and it works.

I replaced an older one that I've had, which worked quite well for 2 years or so. I had a fishy emergency and left the heater plugged in and put of the tank. This overheated the unit and caused it to fail. My mistake. Be sure not to do that. However, the one I killed always kept my 2.5 gal tank at a perfect 72 degrees. This is NOT a good product to use in a tank under 3 gallons. It gets far too hot, even with proper circulation. I will purchasing a larger tank to replace the 2.5 gal and I will be putting this heater back into that tank. Over all, this product works well. Maintain good water circulaton and probably ensure its at very least 3 gallons or more. ## Frequently Bought Together - Aqueon Fish Tank Mini Heater, 10-watt, Plastic - Aqueon Betta Falls 3 Section Aquarium Fish Tank With QuietFlow Power Filtration, Black - Aqueon Fish Tank Aquarium Flexible LED Accent Light and Bubble Wand, Multi Color, 14 Inch --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/2334390-aqueon-fish-tank-mini-heater-10-watt-plastic](https://www.desertcart.pl/products/2334390-aqueon-fish-tank-mini-heater-10-watt-plastic) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-26*
