Swim Bladder Problems

[Cherrehbeareh]

Okay, so my poor fish I'm sure is having issues with his swim bladder, I just have no clue how to try and help him. He just sits at the bottom and doesn't move unless I get his attention, and then he comes up to the top but floats back down rather quickly. He ends up on his side on the bottom most of the time.

Any advice that you can give me at all would be very much appreciated, I just feel rather helpless watching him like this.

Is you betta bloated? Why do you think he has swim bladder? I'm just wondering because his tank isn't heated and there needs to be more water changes than once every 2 weeks for a 1 gal. This might be a factor for him feeling sick.
