Thanks for reaching out about your fish. It is good to remember that all these antibiotics are not absorbed systemically through the water, and placing these antibiotics in the water will likely damage your biological filter. Many, many things can cause swim bladder disease, few are bacterial in nature. Therefore antibiotics won't fix the problem. These medicines should only be used after a diagnosis or suspected diagnosis made. Using antibiotics indiscrimantly can create superbugs, with resistance to multiple antibiotics. Good luck.
