I saw my angel fish laying on his side on 01/31/2022 and now it is 02/02 and since I first saw him, I put him in my quarantine tank with epsom salt because I think it might be his swimming bladder and he has shown no improvement at all, is there anything I am missing or something else that I can try? Thank you for your help!!!!(His name is smokey and his lady Monet is missing him very much and needs him back home)
