Heaters for 1 gallon tank

[RoMay]

I use the Marina Betta Mini Heater I got at petsmart for Kaoru. While a small covered tank will over heat I discovered by adjusting how open the lid is I can adjust the tempriture so I have no issue. It also remains pretty steady. It's not flat so a betta may nap on it but it doesn't get to warm so you don't have to worry about the betta cooking itself. If you go to amazon you can find many other types, but honestly I never liked the flat ones due to I never got one to work.

It worked for her when she was in a tupperware dish, a half gal, and she's in a gal. now.

It's not a good idea to use a 25w heater in a 1 gallon because it will heat up the water VERY quickly. Any time it fails, your betta will cook :( Unless you plan on watching the tank literally 24/7 it's very dangerous.

What about a 50 watt in a 5 gallon?

I had that same heater in my 1 gal. and the same thing happened. Then I decided to move that one to my 2.5 gallon and move my Hydor Theo 25 watt adjustable heater from the 2.5 gallon into the into the 1 gallon, and it worked great!

I'm recent to Bettas, tho here are my heater experiences within two weeks. (non-adjustable heaters) Btw, my tanks are on a window sill in NJ (December)
I adopted my Betta from 1/2 gal bowl. First went to temporary 1 gal glass goldfish bowl with a Battatherm 7.5-watt round under gravel heater, recommended for 1-3 gal. Remains constant 78-80 degrees. Then I got a Fluval Spec 5 gal and a Top Fin 15-watt flat heater I also put under gravel. Recommended for 5-10 gal Stayed at 74- degrees. Upgraded to a Tetra HT10 50 watt cylindrical heater recommended for 2-10 gal. Stays at fluctuates from 74-78 depending upon conditions. Now the Fluval is a long narrow tank with large surface area by the window. At late afternoon I put a 2-inch thick styrofoam sheet between tank and window which raises temp a couple more degrees. I just got a Marineland 2 1/2 gal today and put the Top Fin heater in and is at 82 degrees, tho not in the window sill yet. Hope this helps at all.

A lot of people have used the hydor theo 25 watt in their 1 gallon with great success. Adjustable is really the way to go.

I also had problems with the aqueon. I wound up getting an adjustable light timer from walmart and set it to run for 15 mins for every hour and it kept the tank at a constant 80. I like that a lot because it could never overheat my tank. Its like a little 5 dollar fail safe switch.

I pick up that little betta marina heater and it was much better. very stable temp.

as long as its adjustable the wattage is no big deal. I have a 50w adjustable in a 2g and it hold steady at 80 no matter what the room temp is. adjustable is the key word though...
