Hello all,

I've known that the Corydoras species don't like the medication so much, but they are especially sensitive against the malachite green and salt. On the other hand, I've seen in some of the previous posts of this forum that some hobbyists use and advice them. Have I known these wrong so far?

I think Cory is really very sensitive to Medicine and Salt.

But in some special condition, I also add them to cure my cory. In my opinion, the PPM is very important for them.
