Longear sunfish swimming wierd

This year is like the health issue year in my tank... anyways, the longear is now swimming with its head looking down like if it was looking for something on the substrate, but it does this 95% of the time. It rarely swims normal and when it does, it is for about 5 seconds. I noticed it has this white- clear flap in its gills. I just did a 45% water change and dosed prazi pro. Anything I can do to save its life?

I hope your tsn gets better. My longear sunfish died the Sunday after I started this thread. He was 6.5in.

Is your tsn better? I'm just glad the longear sunfish didn't have to suffer anymore. The swim bladder infection looks painful and stressful. I think my other fish are happy since he was the king of the tank and told everyone what to do. I got my longear at 1.5-2in long. At least my other fish are healthy.
