No I haven't seen any scratching. They have been in the tank for a couple of months now. I did put in 6 glowlight tetras two weeks ago. Another cardinal tetra looks like hes got one starting in the same place. It looks more like a pimple starting under the skin and coming to a head rather than salt. Should I treat for ich just in case?
