If anyone has any experience with gill flukes then advice would be much appreciated. I have been losing roughly one fish a month for about 5 months. All are various types of danios. They start off by stopping eating. Spitting food out. Getting very thin. Basically wasting away then eventually floating around and dying and ending up in a curver shape. Anyway one of my glowlight danios is now doing the same however its gills are red and its belly underneath is red and its belly is very sunken in. Is this potentially gill flukes?
