This one??

Or this one?

Answer 1

I'd go with the more common brand (Pennplax).

Having said that, I would suggest you go to thatfishplace.com and search for the brand Ebo Jager. They are known for the best aquarium heaters.

Also, if you haven't obtained your 5 gallon tank yet, I'd go for at least ten gallons.

Answer 2

Pen Plax.

Answer 3

Penn Plax and I'm ony saying that because I can see it has an adjustable thermostat.  Make sure whatever you get has that.  The ones that regulate heat themselves are set on one temperature and you need to be able to change it based on the fish you will have.

Answer 4

I agree with the others. It should say how many gallons each heater is for somewhere on the package. The adjustable heater is a big plus. Sometimes you get what you pay for though. If it was my tank, I would go for the second.
