I'm a new betta owner, and new to the forum. I've only had my betta for four days, so I hope I'm not obssessing too soon.
I have him in a 1 gal tank (am going to get him something a little bigger, but he seems happy swimming around this one for now). It has a low flow filter, heater, lid, and I conditioned his water. He eats mostly freeze-dried bloodworms, which he loves.
He is generally perky, likes to hang out at the top of his tank and swim around his plant, seems happy. Based on everything I've read I think he's doing okay. All his water perameters are good.
Today he has been resting on the bottom of his tank a lot. He doesn't seem lethargic, and he jumps up and swims around frequently, but he is resting on the bottom of his tank, and often underneath the heater. The water is 78 degrees (the heater is factory set to that temp).
Is he cold?
