hello, this is my first post but ive visited the site very often to read advice, its been very helpful. Anyways my betta Frank has sever swelling on the left side of his abdomen, he sits at the bottom of the tank and leans on the glass. He only swims for air, and he is not eating at all. About a week ago I left a pellet in the tank and it looked like he might have ate it, but i couldn't tell, im not sure the last time hes ate probably a couple weeks (i take the food out when he doesn't eat it though). Now a few months ago we had him in a 1 gallon tank with no thermometer and were him feeding way too often, and he was really bad. fins clamped, very lethargic, laid at the bottom of the bowl, floated on his side as though he was dead, sometimes looked as though he wasn't breathing, and there was the swelling also. One of my family members was also treating him with pimafix during this time for a couple days but i stopped them cause i read it didn't work (although its a possibility it was helping him, but im not sure). So I did my research and cleaned his 1 gallon bowl, put the conditioner in, put epsom salt in, and tried to keep him as warm as possible. After a couple days the swelling went away completely and he seemed to be a bit less lethargic, but was still not eating. About a couple days later we got a 3 gallon tank with a thermometer, heater, air pump, and a small filter, and i added epsom salt but not as much as the last time (i put very little). He seemed to be even more active (but still a bit lethargic), and his fins weren't clamped, also the swelling was still gone, but he was still not eating. (I know they wont eat for like a week after a tank change but its been well over a week). So now after a couple weeks trying to feed him he still hasn't ate. I tried switching it up with blood worms,using kents garlic extreme but he seems to have no interest to eat. Also the swelling came back, and its pretty bad. I tried kanaplex after water changes but doesn't seem to do anything. I don't know if he has ammonia poisoning from when he was in his 1 gallon bowl, or if its dropsy, or swim bladder, its hard to tell. oh and his scales are not pine coning. He also does this thing every once in awhile where it looks like hes gulping. He looks up and opens his mouth real wide. I don't know if that's normal or not. i do a 25% water change twice a week, one just a water change and the other i use a gravel vacuum. ammonia is at 0, and all the water parameters are right. I think im doing everything right, but i just don't know what im missing. Please help.
Thanks
