Oranda Goldfish constantly floating?
I have a male Oranda Goldfish ( Mr. Bubbles btw). I have had him for about a year and a few months. He is now a pretty good size, being about 4 inches from his mouth to the tip of his tail. I have had him in a 10 gallon tank, and monitor the PH levels (which are very healthy). I currently add "freshwater fish safe" salt to his tank due to past fungal infections. I have him on a steady diet also, feeding him Aqueon goldfish granules each night. But he constantly floats! And it is starting to get bad! Should i get a bigger tank? And if so, isn't that risky??? Please help me!
