2 gallon betta bowl with 20 gal heater?

[mvigor]

I'll have to find an adjustable one.

I can't set my thermometer for 80 because it's not adjustable. That's why I need to buy a different one. Main reason why I haven't is because I don't want to be out almost $20 (when you include shipping) for a heater for a stupid little 2 gallon tank that I should just throw away. I'm such a packrat. I'll wait until I'm putting in a big order and add the heater in too.

mvigor, the Visatherme 25w heater is adjustable and I bought it at walmart for about 8$.

This isn't the one I have (mine aren't submersible) but here is a link to one kind of them. 6" long.

By the way, it'd help if I learn how to spell Visitherm
