Hi, I have had my male betta, Bam, for about 3 years. He's in a 2 gallon, filtered tank (weekly water changes) and eats betta pellets. Over a week ago I noticed he had a lump on his stomach. I wasn't sure what it was so I treated his tank with a anti-bacterial/anti-fungal. No change, so I went online and saw it could be constipation. The lump on one side is bigger than the lump on the other side, but he definitely has lumps on both sides. He seems normal and active besides this. I fasted him for 3 days and then fed him the mashed up insides of a pea last night and some this morning. Still no change by this evening so I gave him an epsom salt bath - the "hospital container" I used was a little less than a gallon and I used 1 teaspoon espom salt (I was nervous to put any more in there as I don't want to hurt him) and left him in the bath 20 mins, then put him back in a clean tank. Again, his behavior after this was also normal but he still has these lumps on either side. Any advice of what it could be or how to treat this? I'm attempting to attach a pic here:
