I have 2 fantail orandas, and one was purchased about 6 months before his friend.The first goldfish has swim bladder issues that I can control with a diet of peas and goldfish pellets.
However, he seems to be listless and only moves a lot when food is present, and or when I walk and look in the tank. They both have the right amount of gallons per inch- they are both around 2 inches, and have a filter and have regular water changes-20%.
My question is that he is sluggish , and is there more info out there on diets for goldfish that have swim bladder? And what could be making him so sluggish and sit on the bottom with his dorsal fin down?
