Scraping doesn’t kill the fish anymore than scraping your cheek for a dna test would kill a human.Hi guys, thanks for all the replies. I'm trying my hardest to save the fish. Its been in the hospital tank for 3 days now and wont eat swims head first down nearly all day besides at night when I see the fish swimming sideways sometimes. I think something might have spread to the bladder because of some bounces issues also the gills I noticed were inflamed around the same time and shes breathing heavy for the past 3 days. It looks like the entire fishes is being affected. The only things ok are the eyes, nose and head are perfectly clear. I've been treating with paraguard on day 3 no improvement it said in their forums to treat "a wide range of bacterial infections." Now I can see the fish up close there are zero not one white bumps or spots on the fish. Brooks/velvet all of them are out. I'm thinking about switching to API Furan 2. I read online if one bactericidal medication doesn't work after 3 days switch to another. Any thoughts? Far as buying a microscope and scrapping the fish I don't exactly want to do that that could kill the fish. Any thoughts?
