I sent you a private messageHere is what I’m seeing; mucus plugs and ich. The larger, elongate spots are mucus plugs being extruded from the fish’s skin. However, I see smaller spots on some fish, especially on their fins where mucus plugs don’t develop. Flukes won’t show as worms, they are small and/or clear. Flukes are seen by the damage they do. These fish could well have flukes, just that the white spots aren’t a symptom.
So - what to do? The tank doesn’t seem to have a lot of coral in it - can you move out the invertebrates and treat the whole tank with hyposalinity? The other option would be to move the fish out and treat with copper. The third option would be to finish the second prazi treatment in 8 days and hope I’m wrong in seeing ich here….
