My clowns have been in QT for a week and a half now and I did a 50% WC on Wednesday and dosed cupramine. Up until this morning I noticed one of the two clowns swimming erratically and now he's just at the bottom breathing rapidly. My parameters are all in check except I had a trace of nitrite at 0.1 so I did a 50% water change. My other clown is perfectly fine and even attacked the pipette when I checked my parameters cause he thought it was feeding time I did notice the healthier clown nip at the sick one a few times but his fins or body aren't damaged or red or anything.
What should I do? And should I redose cupramine to my original levels?
