Small Heaters for a 6 gallon Fluval EDGE tank
I just bought a Fluval Edge 6 gallon tank to upgrade my shrimp. I know that they are fine at my 66-70 degree F room temperature, but I was thinking that if I wanted to get some nano fish at some point it would be a good idea to get a heater for the tank. I have an Eheim Jager 25 watt heater that was just sitting in my closet, so I thought I could use it, but it's 9.5 inches long and would stick out the top of the tank, not to mention just aesthetically it's HUUUUUUGE in there.
So I was wondering if anyone out there used a heater in their Edge, what brand/size it was, and where they arranged it inside the tank. And I should add that I would really only want one with a thermostat, because my room can get hot in the summer and I don't trust something that is just "higher than room temperature."
