Quarantine question?????????

If you use an active quarantine process (e.g. copper or hypo for protozoan control and Praziquantel for flukes) a six week time frame works well. If it is an "observational" quarantine (e.g. you just isolate the fish and don't treat) I would go a LOT longer.
I used to use the standard "30 days" - but about 25 years ago switched to six weeks and have avoided lots of problems. Also - any active disease during the process resets the time to zero....

Basically i bought a very nice and healthy looking blonde naso tang.I put him in my 20 long quarantine tank.He looks very healthy and eats proper he has been in there about a week and a half.
So your saying to keep him there for longer then six weeks.If He had any parasites or other in the water he came in or on him wouldnt there be some sign of it by now?

Well,
You may be in a bit of a bind - if the naso is the one in your avatar, it isn't going to appreciate being in a 20L for any real amount of time. You might get away with quarantining a 3 inch naso in a 20L, but much more than that may be a problem.
Like I said, copper (or maybe hypo) and prazi is the way to go - unless you have a FOWLR and can treat disease directly in the tank if need be.

I think QT treatment would be different for what type of treatment is done before you add fish to DT. I do a 6 week QT which involves eradication of ich with quinine sulphate and a prazipro treatment.

No its not the naso of my avatar pic.But he is pretty big maybe 4 inches or so.Why should i treat him if he shows no sign of sickness,Wont that just stress the fish out.And i thought ich can only last a few days without going through its life cycle which you would clearly see it on the fish at one point?

+1 I too try to avoid copper as much as possible, I only use it if the fish needs serious medical attention.

Can you please provide some documentation to support your claim that copper shortens the life span of fish. This is the first time I am hearing this.
Yes, the only time copper "shortens the lifespan" of a fish is when it is used incorrectly and you kill this fish(grin). I've used it on tens of thousands of fish over 40 years and the only problems are with pygmy angels, seahorses, mandarins and a few others. Even those can be treated if you are careful.
One month is not sufficent because it takes two weeks to treat with copper and three weeks for a full course praziquantel treatment.....

Re: using PraziPro
During this three week treatment do you redose every 5-7 days? or is once enough and leave it w/o water change for 3 weeks?
RegalAngel,
For praziquantel, we dose at 2ppm (sometimes 2.2ppm) and then 10 days later, perform a 50% water change and re-dose. Another ten days and we do another 50% water change. We used to do this on a 7 day schedule, but found that some neobenedenia eggs were getting through the process.

Just trying to understand the reason for the water change and then redosing? Not sure what the purpose would be, but seems like simply leaving for 20 days would achieve the same? Is it for reelevating pH, or is it to restablish the orginal concentration assuming it is reduced due to time, adsorption by rocks, etc?
Thanks for the info.

RegalAngel,
The 50% water change is just a guess based on experience by the people who originally put this treatment together at public aquariums. Prazi is lost from the system at some unknown rate, and overdosing can be problematic. Doing the partial water change and redosing at the ten days ensures two things: there is a killing dose for the flukes on day 1 and 10, and that toxicity from an overdose won't occurr. I know that single doses won't break the life cycle of Neobendenia. What I don't know for certain is if the 50% water change is actually required. The only way to test it would be to skip it and see how the fish react. Too risky IMO.

For me, at least eight weeks of active treatment to eradicate ich.
Six weeks might be sufficient, but I also go at least eight weeks, often longer. The work in QT is in the setup, after the correct setup a fish is not more difficult to look after in QT than in DT.
For difficult fish that do not eat prepared food well soon, I have to isolate and acclimate first before treatment. This is because treatment against ich will kill the mature LR I place for them to pick on. For this difficult fish, an isolation/QT process can be three months long in the QT tank.

Hi, sorry to jump in, but how do I measure ppm of a praziquantel treatment?

So should you do both Hypo and Prazi at the same time? If you kept the fish in Hypo and dosed Prazi (2 times) would a 5 week treatment time with one week to slowly bring them back to normal salinity take care of most anything that they would have? What diseases could survive this?

2 milligrams/liter = 2 parts per million(ppm)
1 pound/gallon = 120,000 ppm
As you can see it won't take much praz....
You will need to weigh the praz to determine the milligrams/liter needed for your tank.
