Yeah, I bought one of those and had to watch the temp like a hawk to keep from boiling Batista during the day. It just raises the temp 2-5 degrees from the room temp.AlexsDaddy said:Walmart sells a heater for small tanks called the Jr. heater or something like that. I don't like it though cause the temps not adjustable and you still get temp fluctuations.
Before you get a heater, get the thermometer and check the water temp. If it is not too cold you may not need a heater. I have to use one in my house for my betta because my husband likes the house cool, but I don't use one in my office tank because the boss and I both like it a little warmer and Hunter's tank stays about 74 with no heater. He is by far the healthiest of all my fish.
Several of the members here who breed bettas don't recommend using heaters. They have found that their fish are hardier with a little temp fluctuation. So you might want to take that into consideration as well.
Hope I haven't made things more confusing.
