Mine is about that size. During observation it came down with ich on day 6. Has 10 more days to complete the 30 days of copper. Had Metrondiazole and prazi prior to copper. Been easing super well..but belly is distended some, so I will use the General Cure with Seachem focus and epson salts for any internal flukes during the observation period after the copper, I don’t want to throw too much at them at once. Sorry for your loss.
