Ich develops DURING Copper Power?

[LeonThePeon]

I got some purple tangs from my LFS and went straight into QT. I’ve been treating with 2.5ppt Copper Power since December 3. No signs of ich or other diseases I could see.

About a week ago I noticed what looked like fuzzy spots on them - I’m presuming it’s Lymph. I upped my water changes and it seems to be getting better.

there’s still white spots, but just in case it is ich - can ich survive in copper to begin with? No ich when I got them; no signs of ich for 2.5 weeks or so. If ich was on them when I received them - wouldn’t it have shown earlier?

but more importantly - can ich survive in the water column with Cooper Power at 2.5ppt? (Hanna verified)

I was going to ease them off the copper and just keep them in QT - but now I don’t know whether I should just keep them in copper?

Can you post a picture?
When I hear of ich surviving in copper, it is almost always associated with test inaccuracy - unlikely here since you have a Hanna.
It could be Lymphocystis, but tangs also can produce white mucus plugs as a reaction to copper. These spots are larger, don’t show much on the fins, and tend to stay in the same location day to day.

Regarding your copper question. Copper at 2.50pm is effective against eradicating the parasite, but meds can't fall below or the clock starts over. I know copper power has a larger range of therapeutic levels from 2.0 - 2.5 but I hold mine closer to 2.6ppm just to be safe.

Make sure you add copper into the freshly made saltwater prior to conducting your water change, that often causes an improper QT. If you are confident copper was administered properly, then you can technically place the fish into a sterile tank after 14 days but if you're using the same tank, you need to hold off for 30 days before you ease them off copper.

Yup - been monitoring the copper levels the whole time and I also pre mix + test new water going in during water changes. Maintained 2.49-2.55 in the tank the whole time.

Any pictures or video under white light ?

Sorry for low quality photo - not great of glass to shoot pics through.

Not ich in my opinion, it looks like lymph or excess mucus and HLLE. Have you treated for flukes?

Distributing any strange behavior, like excessive yawning, flashing, scratching, etc?

I was going to do a Prazipro regimen after I finished with the copper. I know you can technically combine the two - but I think there’s already a lot going on with just the copper. I was going to water change out the copper water and start it then.
No strange behavior. Eating fine. Swimming around the QT tank all day.

By the sounds of it has been over 30 days at therapeutic level between 2.49 - 2.55ppm. If so you are good to start removing all the copper and start your 2 rounds prazipro 7 days apart w/ 25% water change between doses. Its a sign good that they are showing any other symptoms.
