Thank you for the reply. I was thinking the same thing. Yes, she does, but she also hasn't eaten in the last 24 hrs. I've never had a fish with a parasite. I actually thought about euthanasia, just bc it appears painful and she looks miserable. I added aquarium salt and raised the temperaturea little, but have nothing else to isolate her, treat it with, or know what is the best course of treatment to purchase when I get to the store. Any suggestions on that would be helpful. It's my daughters tank and she's worked really hard to making sure the fish are cared for. We had no deaths for 8 months until the last week.
