Looking for 5-10W heater with thermostat

[Tempestuousfury]

My betta hasn't been doing well and is exhibiting the clamped fins and flicking that is consistent with ick. I've purchased the medicine, but I need a heater that will get the water over 82F. Google has not been helpful in finding a decent product. Could someone please direct me to a site where I can find a heater that will work?

TIA

I have not come across heaters below 25w, though that doesn't mean they are not available. What is the tank size?

2 gallons. I suppose 25 would work, but I don't want to risk cooking the betta...

The Aquael easy heater is one of the best on the market the 25 wat is perfect for your tank

Why would it? the thermostat will cut off at what ever temp you set it to.

Well, I have to say that I have heard of failed heaters, thermostat or not, and literally did cook the fish (this has happened with new heaters as well apparently!)

So the OP is right to be cautious and its only through asking advice and from own experience will he learn what to look out for.

But anyway, I have come across heaters below 25w, but always a fixed heater, not with adjustable thermostat.

A 25w will be ok to use in a 2 gal tank which is about 7.5 litres, a bit on the small side for a betta but doable.

General rule being one watt per litre of water but of course there are exceptions.
And with thermostat heaters, a lot of them are not 100% accurate, meaning you may set the heater at 78F but reality is maybe being a couple of degrees warmer or colder, once you have found the small margin of error, you simply adjust the thermostat accordingly.

Yes of course a failed heater can do that, a failed 25 wat will do the same as a failed 15 wat overnight, Its a risk that everybody in the hobby runs when using a heater in a tropical tank but good quality heaters like Aquael are less likely to fail than the cheap stuff, you really get what you pay for.

Indeed, very true.

If it's only two gallons why not try a plant heat mat under the tank, they come in lower powers.
