Fish observation

[icliao]

I have several yellow tang and a Sohal tank in a big quarantine tank for 2 weeks. Cupramine was administered along with Prazipro from the beginning. Due to water quality problem I moved them to another quarantine tank without medication. All fish have not shown any symptom of white spot or fluke. My question is should I redo the Cupramine treatment or just observe the fish without medication for extended period? Say if the fish appear healthy after 60 days, can I be sure they are ich or fluke free and will not be a carrier of disease even though they have no visible sign of the sickness?

I would do two treatments of prazipro over a 7 day period. As far as ich goes, the fish should go thru cupramine for 30 full days... since they aren't in cupramine anymore, yes another 60 days of observation will be enough time for the ich to show itself if present

If the fish appear healthy after 60 days does it mean they definitely have no ich?

No, they could just have immunity to it and not show outward signs like spots (ich starts in the gills and shows no signs really, it is difficult to tell if a healthy fish without a compromised immune system has ich or not) Its best to treat them with something if you want to be 100% sure they aren't going to carry ich into your DT. If you don't like cupramine you could do TTM or Chloroquine phosphate

I do agree with above but technically speaking you can move the fish out of copper or CP after 14 days of being in full therapeutic treatment THE WHOLE TIME (extremely important) as long as the fish gets moved to a sterile clean tank which has been setup at least 10' away. Only the fish gets transferred and no equipment with minimal water as possible to prevent cross contamination.
The fish would need to be observed for at least 4-6 weeks after.
