My roommate and I have had our Betta Edward for a little over a year now. We change the water about once a week, and the water is at room temperature (its a plastic tank).
For a while now he hasn't been swimming around as much, he just kinda lays in the fake plant in the middle of his tank. He is still eating (Aqua Culture Betta Pellet Food) just not as much. He doesn't swim around much at all. Some times he just lays at the bottom of the tank.
Then today i noticed that he had what looked like little pink lumps on his body. Several on his back and side. I am very worried about him. Does anyone know what the problem might be or what we can do to make him better? He use to be a wonderful little swimmer and a great joy in our little college dorm room. Below are some pictures. In the second one you are kinda able to see the lumps on his side. Just want to make him better.
