Prazipro & fish appetite

[George]

I would leave the fish in PP water for the length of current transfer which is 72 hours. The fish won't die in 3 days if it was eating before the PP.
Sounds like you are doing PP back to back. You might want to wait a few days (anywhere from 3-5 days) between 2 treatments. The idea is PP can't kill fluke egg. The few days between treatments are there for the egg to hatch.
