The inner chip manages it from the inside all it requires is plugging it in and placing it in your bowl or tank ### ⭐⭐⭐⭐ 4.0 out of 5 stars So far so good but suction cup broke after awhile *by E***. on Reviewed in the United States on October 14, 2022* Great little heater for Betta fish in 2.5 gallon tank. Temperature remains consistent. It’s easy to clean during tank changes. The bottom suction cup broke after several months but the top suction cup is still going strong. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars PLEASE READ BEFORE BUYING *by A***R on Reviewed in the United States on September 14, 2022* Okay so I saw ALOT of reviews about their fish dying and I was scared at first but I took the chance. I am pretty good with Beta fish now for years and I had a hunch but I wanted to see for myself. Although this product states it can work for a 3 gallon tank DO NOT buy it unless your tank is 5Gallon or more ! It is too powerful for anything smaller. I hope this helps save some fish lives. The decor was really cute and it is a great deal otherwise I have it set diagonal and it’s doing a great job in our AC blasting condo ! --- ## 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.tn/products/134454865-betta-fish-tank-heater-25w-mini-aquarium-heaters-free-2](https://www.desertcart.tn/products/134454865-betta-fish-tank-heater-25w-mini-aquarium-heaters-free-2) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-11*
