Alright this may sound cheesy but I have had this feeder goldfish for about a year and a half and I've became farley attatched to her. I was looking at her about 2 days ago and she's got what looks like blood under her scales. Does anyone know what this is and how to treat it? (and right now she's in a little emergencie 5 g away from all the other fish)
