Took a look at my fish before going to bed. One of my eldest Tetras (neon) has a single white spot on its forehead, which wasn't there earlier today. The other eldest fish (cardinal, lfs accidentally mixed one in... lol) has a couple small ones on one fin. They are acting normal.
I did buy about 12 new tetras, but this was almost a week ago. So tomorrow I can still swap out the tetras tomorrow to avoid an outbreak. They definitely havent reached freeswimming stage since these spots just shown up, so getting rid of them now might fix the problem.
I want to avoid medication, I have salt and can turn up the heat. I will do this immediately, slowly, just incase. I'll continue to monitor the other tetras and see if more pop up. I have lots of aeration.
