Treating with prazipro after paraguard

[Aquarist007]

I took over a 90 gal tank that had two large damsels, two small damsels, a clown and a large sailfin tang. It had little to no live rock so I built a reef with rock I had in my own systems for a year.

I added a foxface, nasotang and an anthias.
In hindsight I should have removed the big damsels as re arranging the reef must have upset them so they became agressive and took out the nasotang and anthias.
Following this the sailfin tank broke out in either velvet theflukes in my inference.
I treated the tank with Paraguard which did not hurt the corals but took out a long spin black urchin.
The corals showed signs of irritation but came back.

Since paraguard has not made a difference to the sailfin tang and it has been over 8 days now I am assuming it is not marine velvet as previous experience with that has demonstrated a shorter fatality rate on first signs of the parasite

I would like to treat with Prazipro but am wondering if it will hurt corals and anemonies.

The owner of the tank wants me to remove the damsels now and I have informed her that it will stir up things in the tank again as I will have to remove most of the newly installed reef.
This gives me the opportunity to treat the tang separately as it can be removed at the same time,
However I am aware this will cause further stress plus will not address the issue of flukes or parasites in the tank itself

Any advise on what course of action I should take in this particular case

The only thing Prazi might kill is any tube worms/feather dusters in the tank. And even that's not 100% of the time. I would be more concerned about the interaction between the Prazi and the ParaGuard. I've never used ParaGuard before, so I'm not sure what's in it or how long it stays active in the water.

What symptoms is the Sailfin Tang displaying? If he has Flukes you should see: head twitching, swollen stomach, white stringy poo. If you can remove him and give him a f/w dip, you should see the Flukes fall out and settle at the bottom.

I suspect you're going to have ongoing problems with this tank. It is not nearly big enough for a Naso or Sailfin Tang, or more than a single fish of most anthias species. Lack of space =stress= less resistance to disease & parasites; and aggression.
