Can someone give me some advice regarding the gill. This fish didn't look right the past 2 days. she wasn't very active, so I decide to bowl her up and look. She look fine. but I open up the gill looks like the gill is a little damage. is there a way to treat this? I change water 10-15% per day.
ph 7.8
ammonia .25
nitrite 0
nitrate 0
