Reddit reviews Aqueon Submersible Aquarium Heater

I apologize if my post came off snarky, but bettas are a very misunderstood breed. They belong in a min. 5 gallon tank. I've seen others raise in something as small as a 3 gallon tank, but it was not worth the maintenance they had to keep up on. Bettas do best in 78-80 degree water, so a heater and thermometer is mandatory. You want a filtration system, but you want to be careful with the current as something too strong will stress them out. Bettas are not the best swimmers because of the weight of their fins, so most bettas will began to bite them off to lessen the load. As others have suggested, you want to test the water, either by bringing samples to your lfs, are buying a kit, which I prefer. You will also want to cycle your tank to avoid ammonia spikes. I've added links to some helpful things including illnesses so you may be able to diagnose with a little research.

I also have an Aqueon, it's a bit different though. The 100 watt version works really well in my 40 gallon breeder tank! http://www.amazon.com/Aqueon-Submersible-Aquarium-Heaters-100-Watt/dp/B000YAJK02?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_search_detailpage
