Hi! My veiltail, Apollo, DEFINETELY has swim bladder (probably from INHALING his food, he is very enthusiastic.) Online, the treatment for non-bacterial caused swim bladder seems to be to lower the water level and increase the water temperature- Two questions- My heater doesn't have a way to adjust the temperature, how essential is this step? Second, how can I continue to run my filter at a lower water level? Would I be better off just getting him a leaf hammock?
