OK, so. I rescued a beta from some friends about 6 months ago. I just recently moved him from a GIANT fish bowl (probably about 7 gallons of water). I'd had a live plant in there that had died and was probably putting out a lot of nasty stuff in the water. Now he's in a 5 gallon tank with elodea. He's got a heater which keeps it about 80 to 82 degrees in there. He gets afternoon sun, but not directly on him cause hes on the other side of the room from the windows. I moved him on Sunday the 12th to his new tank.
I'm posting this because I've noticed that he doesn't swim around as much as he did when I first got him. He lays in the corner behind his rock under the heater. When he does swim around its like he cant keep his bottom end up and it's a really big struggle for him just to get from the bottom to the top to breath. He doesn't get excited like he used when I come up, and he barely eats when I give him food, I mean, he eats it but not as fast as he used to. Hes also got a few two spots on his right side where it looks like his scales are coming off, but those are the only two spots that I can see and he hasn't gotten any new ones. He's also got a stretched out belly, but I think that might be because I used to fee him too much, but it still hasn't gone away. He also hasn't made a bubble nest in about a week, which is worrying cause he used to made huge ones that covered the whole top of his tank.
I have absolutely no idea what to and I'm always terrified I'm going to come down and find him dead.
