Heater in 2.5 Gallon Tank

[imaginelra]

I have a 2.5 Gallon Tank with one male Betta in it. I want to get a heater for it but I don't know how many watts to use for a tank that small. Any suggestions???

Use the smallest heater you can find. 25W should work well.

I used a 25W in mine. It's large and gaudy, especially compared to the size of the tank, but it works.

I'd get a marineland stealth pro mini heater, 10w. It automatically turns off when the temp reaches 78, unlike other mini heaters that stay on all the time that you have to unplug and replug in. It's preset to 78, that's the only down side. It's very small so it'd fit your tank nicely.

There is also the Hydor Mini Heater which I have in my 2.5 and it works perfect.

Great, but dont they constantly heat, and don't turn off at a certain temp?so like if the temps already 79, theyll continue heating?

That's correct they don't turn off at a certain temp, I'm not sure what they are preset at but if the heater only heats to 79 and the water is at 79. 79 degree water wont get any hotter if in the presence of 79 degree heat they would be in balance.

Get a heater with an adjustable thermostat. Cheap heaters (including pretty much all non-adjustables) use a cheap thermostat that's insulated by glass, a poor heat conductor. The heater doesn't have a very good idea of what's going on in the tank, so the preset temperature can be way off.

I went to the pet store and purchased the 10 watt Marineland Stealth Pro mini heater..........so far so good, Thank you all.

Good, had it kept the tank at a steady 78, I've been planning to get one.

I'm debating switching my Hydor to one of those, only because I have one in my 29 at home and I love it.
