I suddenly have two super reds covered in these spots they were both clear 24 hours ago. They are on their eyes and bristles as well.
They are (were) in a tank with about a dozen other young adult super reds and some rainbows. No other fish have even one spot on them. The water in the tank tests normal, low nitrates, no nitrite or ammonia, pH just below 7, our water is naturally on the hard side with low kH but doesn’t fluctuate and hasn’t.
they are both now in a quarantine tank. I have the Med trio available, my gut tells me it’s fungal but looking for input or if anyone has experienced this. Thank you in advanced.
