I have a few questions regarding the water temperature in my betta tank. I have a 5 gallon tank in my bedroom and I keep my door closed to keep my cats out. Because I keep my door closed the bedroom gets really hot sometimes. I got a new thermometer because I thought the water felt really hot, but my old thermometer said it was only 78....just didn't seem right. Anyway, the new thermometer said that the water was like 84 degrees! So, I put up a baby gate and I'm trying to get my cats "trained" to not jump the gate so the door can be opened to cool things down. I now have the tank down to 81 degrees and it fluctuates like .5 to 1 degree at night...so it goes down to like 80 or 80.5 (I got a really nice digital thermometer that goes to the tenth of a degree). Is this ok for my betta? Or should I get a fan to keep in my room to cool it down more?
Thanks for any help or advice!
