plz help my angel fish

hey to all. Really hope someone can help my angel. She is breathing normally but there is a blood red line along her fins and she keeps on laying on her side. When i disturb her she is swimming normally. Lfs sold her as a koi angel. Plz any help to save my baby

 

@silverj87 when did you buy her?

 

more than a year ago

 

Is it only this one fish that is showing problems? When I think of a blood red line in the fins I'd usually consider ammonia poisoning. Is there any way that your filter might have had a problem recently? Maybe you could do a lot of water changes for a few days and see if that helps at all. Just make sure you dechlorinate the water...

 

yeah its only the one fish that doing this. Ive been away from the tank for a while and think i must do a very good cleaning session and a couple of wc's

 

Get a few plain water changes done first over the next day or so before you start cleaning the gravel or anything, don't want to make it worse before it gets better. I assume you know not to mess around with the filter media Really hope this works and your angel recovers!
