Anyone have a tank that would be suitable for a betta that they aren't using and would sell? Anything 2.5 gallons to five gallons.
I already have a small air pump with a check valve, but I would have to replace the tubing because it is from a small goldfish tank I had years ago and the tubing is really yucky and brown :-XWell, if you really want one, I'd say to just buy one of those cruddy goldfish tanks (3 gallon plastic) and stick a 25w heater in it. You could also use one of those corner filters. But be careful, if you're using the same airpump as one of your tanks, if your pump turns off then the water will travel down the tubing and into the small tank and flood it, and vice versa. So invest in some one-way valves. I learned the hard way after getting about a gallon of water on the floor :S
