Oranda low on oxygen?
Hi everyone! Looking for some opinions on my Oranda. She is in a 20 gallon take that gets a 20% water change weekly and is tested regularly. Water levels are all normal and this is a relatively new issue so I donít think that that is the issue here (ammonia is 0ppm, pH 7.5/8, nitrates are 20ppm and nitrites are 0ppm. Carbonate hardness is 80 and general hardness is 30). She does seem to be prone to some buoyancy problems with her swim bladder as most fancy goldfish are, however she triggers it by gulping air. I feed her sinking pellets, fast her once a week and feed her peas once a week all to avoid her becoming a balloon. I thought maybe the gulping air was an oxygen problem so I lowered my water level slightly so as to create more water movement from the filter. Any thoughts on why she else might be gulping air and/or how to stop it from happening?
