Can anyone confirm from my microscope pictures these are flukes? I had them before, a few years ago. But this time they don't appear to have the usual shape with a toothed head, just more like a yellow blob. I noticed the fish flashing and found trichodina and also this, the pictures both at the same magnification, but had problems taking pictures. I don't want to treat the tric in case I need to treat for flukes. Thanks
