I believe this all started because of a bad water change. After a water change a couple of days ago my jar's stomach started to get bloated. I waited a day to see if it would clear up by itself but it got worse so then I added aquarium salt and the bloating went away overnight. I waited another day and then started feeding it again. The next day I noticed that the stomach has started to bloat again. That was yesterday. Today, the bloating has gotten a little worse. I've fed the jar but I'm not sure that was the right thing to do. Any suggestions?
