01/20/2023 Treatment in quarantine tank with salt and one course of Kanaplex. Not eats on day 1. Possibly due to stress of change of environment.
01/21/2023 Start eating. At some point during course of treatment, become inactive and possibly not eating / eat less. Stress of change of environment and Kanaplex?

Since he got sick during quarantine shortly after arrival, I was not sure if his getting mild symptoms of fin rot was due to his being sick after travel or stress induced by changing environment in quanrantine tank. Thus I opt to treat him with salt in the main tank and do frequent water changes (now 80% twice a week). While his inflammation and white tip has not progressed, it is not getting better neither. Worse, I notice the slight decrease in appetite and swimming activity. I am at a crossroad of whether I should just continue frequent water change in main tank to wait it out, or proceed to take more aggressive treatment plan, such as courses of Kanaplex in quarantine. Your perspective is much appreciated!
