Heater for a 5.5 gallon tank?

[katie113]

I am new to betta keeping and i would like your opinions on which heater would be the best for a 5.5 gallon tank. I would prefer something adjustable over the ones that have a preset temperature.

Good call. Adjustables are the best way to go. Everyone has a favorite depending on their budget. I like the aquacon 25 watt heater at the low end, fluvals are great top end.

I recommend a 25 watt adjustable Hydor THEO :) I have a 5.5gal too, and the heater works great!

I would get a 25w heater for a 5.5 gallon...I have the 25w Eheim Jager for mine.

I use 50w Aqueon Pro heaters in my 5g, but you can also use 25w. The 50w will just be able to keep temperature a little higher above room temp if you let your house drop cold at night or keep it chilly during the winter.

Hey I was actually just wondering, how cold would one's house need to get for one to need a 50w in a 5.5 gallon?

IMO unless your house is in alaska with no heat, you should never need a heater that big in a 5.5
You wouldn't want it to malfunction and flash boil your buddy!

I second the Hydor Theo. I use the 50W version in my Spec V (yes, it's overkill and yes I love it).
