My betta is about 1.5 years old, and while I was away at school my sister noticed she started to get a lump on her left side. When I got home the water was not very clean and it did not look as if my betta had pooped recently. I did a water change, and for the next 3 days she didn't poop. BUT she has been eating when you feed her, which i have limited because she seems constipated. I have NOT tried epsom salts but I did feed her peas the past two days which, she pooped once and it was a cloudy orange color. Her scales are starting to raise it looks like on the swollen parts.
For the most part she is active, but recently she has started to lay right under the water's surfaces. I believe it is constipation, but normally how long does it take to go down? and If it is constipation, wouldn't she stop eating?
Here's some pictures:
