Is this going to work you think?** A: There is NO fish in existance that can survive and thrive without filtration...even bettas. If you have a betta and no filter, thus no water movement, you are killing your fish. Please...do some research. Don't fall prey to the misinformation that they little guys can live in a puddle. Thats as bad as saying a goldfish can live in a bowl. **Q: Will this overheat a one gallon tank?** A: I bought it for my 1.5 gallon tank and it made my tank 93 degrees it does not shut off like it's suppose too! **Q: It says under 6 gallons. So if i have a 6 gallon round that a bette stays in would it be good for that?** A: Bettas should have a MINIMUM of a 3 gallon tank WITH filtration AND heater. It is a myth that they can survive and THRIVE in anything smaller. They really should have a 5 gallon tank but if the tank is well planted with live plants to help with nitrate removal, they can live in a 3 gallon. Please do research on this. There are lots of good videos on youtube on how to take proper care of a betta and what is flat out cruelty. A bowl is basically the equivalent to keeping your dog in a closet and never scooping their poop. Except bettas have to breath it too. ## Frequently Bought Together - PULACO 25W Small Aquarium Submersible Betta Heater with Free Thermometer Strip, Under 6 Gallon Fish Tanks (Preset Temperature 78℉) - Tetra BettaSafe, Aquarium Water Conditioner For Bettas, 1.69-Ounce, 50ml, Golds & Yellows (16837) - Aquarium Decorations Cave Fish Tank Accessories Rock Decor for Shrimp Cichlid Hiding Breeding Small Fish Bowl Hide Decoration Betta Toys Hideout Stones House（Medium） --- ## 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.sn/products/174013013-25watt-mini-aquarium-submersible-betta-heater-with-free-thermometer-strip](https://www.desertcart.sn/products/174013013-25watt-mini-aquarium-submersible-betta-heater-with-free-thermometer-strip) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-30*
