Sick McCosker sub male

[Bigfish of La.]

i purchased this fish along with a Randall anthia and a female blue star leopard wrasse from LA ( west coast ) and they were delivered Tuesday and were in the QT tank by noon. All fish ate within a couple of hours. All day Wednesday they all appeared normal, but by Thursday the McCosker was flashing and only eating a little so the tank was treated with prazipro at 6 PM. Friday he seemed active at times and then he would hide in the pvc elbow and appeared dead, but his colors were still vibrant. He appeared this way all day Saturday and Sunday morning there was no improvement in his condition. I did a FW dip for 5 min and put him back in the QT. About 10 flukes fell off during his dip, and he exhibited heavy breathing during this dip. Then I added him back to the QT and he appears in slightly better condition.
Question 1. Why did prazipro not work?
2. Are the other fish infected since all were in same QT?
3. Anything else I can do?

There have been a few threads lately on prazis resistant flukes. I think you will need to see about hyposalinity to kill them.

According to the link hypo at 15ppt for 5 days should do it. There is also a link to hyposalinity instructions. Watch the pH, you may need to add baked baking soda to keep it up

Sometimes the heavy mucus coat of a fish, which is not just on the outside but inside on the gills, helps to shield the flukes from the full dose of praziquantel. So the best way is to "first" do a freshwater dip first to knock loose some of the flukes. Check for evidence of flukes. Second, then to treat the full therapy of 2 full doses: Dose with Prazi. Wait 5-7 days. Do 25% water change. Dose second time. Wait 5-7 days. Do 25% water change. Then observe for 7-10 days.

Forgot to mention I did a 7G WC on a 20G QT last night.

Found the poor guy stuck to the powerhead dead.

Why are these people selling infected fish? Yea LA will replace my fish, but with what, another sick fish.

Are my 2 others infected as well? Doing WC and another round of prazipro.

Is it safer to buy from Divers Den?

I have ordered from at least 4 sources. They all come with some sort of disease every single time. Lately I can't get a batch of fish without velvet/ich/Brook/flukes or a combination thereof.

Only safe place to buy fish will soon be Humblefish Aquatics that are disease free, and can be acclimated directly to your DT with no QT.

I would pay extra for a QT fish. I am still going to put it in quarantine but hopefully not wasting time and money treating sick fish.
Is Bobby starting a retail business?

I'm running my first batch of fish thru QT now. Shouldn't be much longer until I am ready to sell to the public.
