Please, help with diagnosis

[Obriy]

I've had a couple of clownfish for a while and added a royal gramma, two firefish and black neon dottyback recently. Noticed dottyback, gramma and one of firefish flashing on their second week in the tank (still behaving normally and eating well). Then, both of my clownfish became jumpy and restless as if something bothered them too, but no flashing. I used PraziPro to treat the tank according to the manufacturer directions four days ago. Three days ago, both gramma and dottyback died and one of the clowns died day latter. I examined their skin and gills, but could not find anything abnormal. Today, the other clownfish is covered in something white and one of her fins looks damaged.
Parameters:
Temp. - 76
Salinity - 1.025
PH - 8
Amonia - 0
Nitrate - 10
Phosphates - 0
Strangely, after all this, both firefish look and behave completely healthy.

Unfortunately, I don't have QT and removing the clown for any treatment that can affect corals is not possible.

Can anyone tell me, please, what could be the problem and what should I do?

How did you apply/how much of Prazi? I ask as Prazi can reduce both oxygn and appetite and may have. Adding an air stone is Highly recommended with use of prazi. I recommended .4 ML per 20 gals of water.
Go with useable gallons as example. . . . 20 gal tank would be 16 useable gallons

The clownfish sure looks like it has a severe case of Brooklynella. That is difficult to treat if you don't have formalin (and that is toxic to people and is tricky to use in a home). Your next best bet is to use Ruby Reef Rally Pro, but in my experience, it doesn't work very well in severe cases like this....

I added 10ml of PraziPro in an AIO return chamber (45 gallon of water in the tank). Haven't heard anything about airstone before. Does it still make sense to add it 4 days after dozing?

So, should I euthanize the clown hoping to save firefish, or are they doomed too? And, if the firefish survives without any signs of the disease, how fast would it be safe to add new fish. How long Brooklynella stays in the tank?

Before euthanizing, attempt 5 min FWD and move to sterile enrollment could potentially buy time.

I've had success with combining FWD and ruby reef pro dips as well. I did conduct three dips 24 hour apart and sterile tank afterwards.

Low oxygen levels doesn’t happen every time, but the air stone is a precaution if it does. The problem shows up 2 or 3 days after dosing. You are probably past the point of it being an issue.

Euthanizing the clown wont help the firefish, they've already been exposed. However Brooklynella does not infect all fish equally.

I would try the idea mentioned of a 5 minute FW dip, move to a new tank and treat with Rally Pro.....

Too late... The clown did not survive the night.

Other forum members have claimed that metronidazole treats Brooklynella. Do you disagree with this assertion?

No, that does not control Brooklynella. It is best used orally to control gut flagellates.
