@Jay Hemdal is prazipro easier on the fish than copper? I’m just curious cause I always use it after using cupramine.
I’ve only had a few reactions with praziquantel over the years, and they all revolves around the solvent used. With prazipro, the solvent is a type of glycol. Bacteria act on the solvents and that reduces oxygen levels. Just adding aeration resolves that. This is the root of the “prazi sensitive” fish - they are just sensitive to low oxygen.

I found a post from Humblefish 2019:
However, I wouldn't dose copper + metro until you hit at least 1.017-18 SG. Both are more toxic in lower salinity. Actually, I think it's the lower pH normally associated with hyposalinity that's the real problem with copper toxicity.

Thank you, Jay Hemdal for bringing this to light. I agree that I’d feel more comfortable doing one or the other. I think I could be possible to use both methods with a PH buffer. But seems risky if you forgot to buffer the ph one day.

Jay, I know it isn't advisable but I treated with prazipro at the same time as copper. I added a power head pointed at the water surface for aeration. After 72 hours of prazipro and 7 days of copper power at 2.51 ppm my orange shoulder tang and gold rim tang are still flashing and scratching. Any Ideas?

The irritation from the parasites can make them itchy for 1-2 weeks even if the fish are parasite free.

Are you going to follow up with the prazipro 6 days after? (You should). Do a 25% water change before the second dose.

It seems like something is still bitting the gold rim or irritating him. He will be fine acting normal and then freak out like something is bitting him and start scratching. I can tell a difference in his behavior when this happens he is stressed out. I don't know if they stop bitting him or something but after he has a freaking out spell and scratching he will go back to normal behavior. I do plan on another dose of prazipro pro seven days after the first dose.

Keep an eye on it. It should stop once the wound heals.

I have a guess, when copper is added to the system most of the cleaning inverts are removed/ dead. That makes the system incomplete/ unnatural. I mean fish do intend to use shrimps or other inverts to clean their body once awhile, just so to remove some dead tissues or so. But under the treatment they kind of have to take care of themselves. That might cause some irritations on the body?

This is a possibility. I am in the process of setting up a 300g tank 96x24x31 and I have 20 fish in quarantine. I have a 55,90 and 20 long set up with fish in all of them. I want all 20 fish finished with QT by the time I get my 300g tank ready. I think that many fish in QT is driving me crazy lol. I am paranoid that I will introduce parasite into my 300 display and if that happens I will never get them out.

I had some fish including a regal angel had cloudy eyes and fungus infection on the body during qt, I thought with the level of copper most of dieases should be gone. But a lot of the fish didn’t make it. And I do see some of them still scratching once a while. So I guess somehow they still feel bit uncomfortable…

All of my fish are eating and I don't see cloudy eyes or fungus on the body. I do still see scratching and the gold rim seems stressed out like he is uncomfortable or irritated.

I had a mimic half black, mustard, floweri they all had very big white ball on their face during QT. Looks like a snowball about 1/8” in diameter. Fell off after 1-2 weeks. The halfblack died, but the other two survived.

Scratching can actually increase after a prazi treatment, but should settle down after three days. You’ll want to redose 7 to 10 days after the first dose. Neobenedenia flukes often require a third treatment to catch eggs as they hatch.
