What I really need is a heater. At the moment I am having to heat the entire *room* to make the water temperature acceptable to him, which isn't very comfortable for me. However, my pet shop (otherwise wonderful people) don't have in-tank heaters that small. There's a possibility of upgrading to one of those 5-6 gallon mini aquaria with heater etc in future, but not until Christmas since I'm unemployed and already feeding the fish a better diet than myself...
Any advice on this from other betta owners? Are there heaters on the market that are suitable for containers under 5 gallons? Is this any good:
