New here. I have my first Betta...which I bought without any research. So I got a betta, a 1/2 gallon aquarium, and then I came to the internet to read. I know...stupid. Anyhow, I read how heating is required. And I couldn't find anything to heat a 1/2 gallon aquarium. So I bought a 2.65 gallon aquarium. Bought lots of other things too this time...including a heater.
The guy at the aquarium shop said a 25 watt heater will be good...I think that is what he had. He said it is set at 79 degrees. I thought great...so I don't have to worry about maintaining the temperature. But now I see that if I keep the heater on...it rises up within a few hours to about 90 deg. At night I switched it off because I didn't want my betta (we named him Anakin, because we love Anakin. lol!) to get hurt. So I checked the temperature in the morning...and it was 72 degrees.
But I read that the temperature should remain constant, and not fluctuate so much or my betta can die.
How do I keep the temperature constant for my 2.65 gallon tank? I am so worried for my betta. We'll be going out for a 2-day vacation on 17th, and will give the tank to my neighbor for 2 days. But I can't expect them to keep checking the temperature all the time. Is there a way to keep a small tank like this at constant temperature? Any kind of heater that can do this?
Also, my fish seemed to be much happier in its small 1/2 gallon tank. He never looked scared. If I went near the tank, he'd go nuts because he knew he was going to get food. Now if he sees me, he gets soooooo scared...bolts like lightening! I hate to see him so scared
. Is it because of the change in home? Will he settle down? Or do I need to put him back in his old home?
