Hello folks,
I was hoping someone out there can shed some light on this. I bought four guppies at my LFS on Saturday, took them home, and put them in my quarantine tank, so they've been soaking in the Aquarium Coop "med trio" for about 5 days now. Today I noticed one of them was acting a bit aloof and not really associating with the others. Upon closer inspection, I noticed that it had red spots/blotches on its side. It also looks like it's passing an internal parasite, so at least the med trio is working on that. But, what are the red spots (see pics). I didn't notice these spots when I bought them. I did read that ammonia or nitrite poisoning may cause these red spots, but my water parameters are fine.
PH about 7.5
Ammonia 0
Nitrite 0
Nitrate 0
Temp 78
GH/KH about 3-4
Any guidance would be greatly appreciated.
