Hi all, Been dealing with ich and velvet but not really asking about treatment this time. There’s one part of the treatment that confuses me. So the lice cycle of ich and velvet says they’re not attached to the fish itself for all that long. Just a few days at most. And copper kills any ich or velvet in the swimming stage. So a fish in copper can’t get any new ich or velvet attached to it once it’s in. No? So why should you wait so long to keep the fish in copper? After the first few days all that was on the fish has dropped off and you know nothing new has attached. So why can’t you call the fish cured and move it straight to an observation tank?
