My powder blue tang has gone through copper, prazi pro, and is about to be done their 21 day 1.009 sg hypo-salinity along with a blue tang/wrasses. It still is going to be 4-5 more days on hypo but I am not sure on why it is still scratching. It also seems to have 2 white marks on its gill area. Does not look very much like ich or velvet though. Maybe just damage from scratching. It eats like a pig and is a great fish except for the scratching . Any advice would be great.
 
Is it breathing normal? And yes they can damage themselves on whatever you have in your QT tank. Does not mean diseases necessarily. Post pics and a 30 second YT video under white lights if you can. That will help show what it is you’re referring to.

If you did coppersafe, hypo not necessary but can you post a video of fish of at least 20 seconds under white light intensity to see what you are describing?
They are susceptible to skin irritation but video will disclose what it may be

Sometimes, fish scratch for no identifiable, serious reason, or just due to residual damage from flukes. Some people think this can also be a learned behavior/habit, but I’m not sure about that.

At 21 days of hypo, all adult flukes will have died. By 30 days, all unhatched eggs will have died.

Maybe I can see something else in a video?

Responding to everyone here, I will make a video and send it tomorrow, as it is 12 am for me currently. When it starts to scratch it also looses some colour. Some days the fish is a dark blue which looks amazing and the fish seems to calm and doesn’t scratch. Other days it is a more light blue and scratches. Kind of weird.

I am pretty sure it’s normal but I will take a video tomorrow

I haven’t watched the powder blue tang that much recently and will try to get the video out soon but it seems to have stopped scratching.

Here is the video, it flashes once near the end of the video. It does this every 10 mins or so maybe longer. The pbt sometimes flashes on the bottom glass too where it turns sideways and flashes:

That was a pretty minor, half-hearted flash. However, there is some cloudiness to the pectoral fin tips that shouldn’t be there. Might be from rubbing on pvc, but could also be a sign of flukes.

One trick you can try is wait until you’re about to release the fish to a DT, then double dose the tank with prazi and move the fish out 3 hours later. That will help if there are a few flukes remaining.

The cloudiness is lympho I’m pretty sure. All spots are gone on the fish and it looks great but sometimes it flashes. I’m really not sure what to do. Do u think the fish is ready?

The cloudiness is too diffuse to be lymphocystis.

I’d wait 14 days after the end of hypo and then, if the fin cloudiness and minor scratch are the same or improved, I’d release it from quarantine.

Ok thanks. My perfectly healthy yellow Cori’s wrasse is dead. I saw it this morning getting eaten by all of the fish in my dt. Have any reason how it just misteriously died. All other fish are fine

The yellow wrasse wasn't in your QT, right? I can't really say what might have happened to it. How long did you have it? Any red sores on its body after death? Was its mouth open after death?

I think it may have been open but not really sure because I only saw its skull like the fish fully cleaned in out. The wrasse has been qt before. I can’t tell if it was open or not because I just saw the bones of the mouth which was a tiny bit open but I’m pretty sure that’s normal. Can u point out the fin cloudiness please because I can’t really see it in person. In person it just looks a bit damaged because I think it’s healing from the lympho or flukes which were previously there. The scratch near its gill is gone and it has no spots at all anymore.

In the video, I can see some cloudiness at the tips of both side fins, not raised up, just a slight cloudiness......

I was looking at it and it may have some little white spots on its fins. I’m still not sure if it’s just the glare from the sparkly lines on its fins but this could help u understand what’s happening. I doubt this is ich and if it was flukes then shouldn’t the fish be getting sick. Plus it’s looking so good. It is grazing algae 24/7, darts at any food that gets dropped into tank. I haven’t seen it scratch since yesterday as well. Not really sure what to do.

Is the fish still in full hypo?
 

I just don’t see how it could still be flukes after this amount of time in hyposalinity. There are some brackish water flukes, but they are rarely seen in the pet trade, because the fish that carry them are not commonly sold in stores - they are more a public aquarium issue.

I am getting some close up photos of the fish and it’s fins. On one side of the body it seems to have lost all the spots. On the other fin it seems to still have the spots or I’m not sure what this could be. Anyways I circled the spots with blue.
