I only medicate when after review, there appears to be a reason.
Otherwise that would be like going to the doctor, he finds nothing wrong with you, but gives you a bunch of meds just in case.
If your going to medicate, be specific, you know what you have and you have the right meds to fix it....otherwise just keep them in 1.017-1.020 salinity during there observation period....I do this for any fish regardless of origin....
