Yes, always quarantine. DD doesn't actually quarantine, only holds the fish for 2 weeks before putting them up for sale. I would do at least another 2 weeks, but since you have no idea what went on before you got the fish, or what other fish yours was exposed to, you should proceed as if it's straight from the wild, quarantining for 4-8 weeks.
I treat all fish with PraziPro and do 6 weeks hyposalinity. It's part of being a responsible reefkeeper. There's no way in years (lifespan of most fish) that they'll never get stressed and become more susceptible to parasites.
Hollister, about 60% of fish come in with some kind of disease. 60%!! Granted, many of these are relatively harmless and can go away on their own, but that is not a statistic I am willing to gamble against, and you shouldn't either. I have have seen way too many people lose their prized fish after introducing just one that carries a disease, even after years successfully not quarantining.

I fully agree and dont say all should do it but if its a trusted source the 3 or 4 days in a QT should be plenty. Atleast for fish ,frags should be longer , in fact depending on the tank i might even desect that frag first.
I did alot of research and felt comfertable adding without QT ,ing. I added 5 fish in a 75 gallon and the rest was coral. I dont even skim. water changes alone do the job. Though i did skim the first 2 years..
There is no trusted source. Stress does not cause ich, ich causes ich. There are many worse parasites than ich, when you run into them, you lose all the fish in your tank. Period. Oh, and for those that check my profile, I have slightly over a 1000 gallons of saltwater tanks. And I have been doing aquaria since 1957 and salt from the early 1980's.
