Sick fish with swim bladder disease

Apr 5, 2018
my oranda fish has been dealing with swim bladder problems for a week now and I have been treating it with changing my tanks diet(from flakes to shrimp) putting salt in the water, and putting medicine in the tank. So far he has started pooping clear stringy poop so I’m wondering if he is getting better. Is there any other way to get rid of it, I feel bad because I have three other goldfish in a 20 gallon tank with three filters and an algae killing light, there is no problem with the tank but just a problem with my fish. Please help/give suggestions.
