Hello all. My planted tank have been cycled for 1.5 months ago and 8 of otocinclus affinis have been added from the first month and so and they've lived perfectly in there. Two weeks later, I started to introduced 10 of cardinal tetras that I bought from my LFS and 3 days ago when I was feeding them, I noticed that one of them scratch its body to the plants and rock a few times make me suspicious if it has been infected with ich/white spot disease.
Today, I noticed that a couples of them have a single or two little tiny white spot (I can't confirm on this 100%) on either tail or fins also some of them become like to hide amongst the plants, an unusual behavior from the 1st day although they seem to feed like normal.
What do you think I should do? If in any case that they are sick, how to cure them in planted tank since some of the plants that I know are very sensitive to medication ingredients. Should I quarantine them in temporary tank, how to make sure that my main tank have free from bacteria when they have been cured and ready to come back to the main tank? Lastly, should I quarantine the oto's too or do they immune to this kind of ich/white spot disease?
Thank you very much for you help in advance.
