I've had a run of bad luck recently and the last fish I bought I put into quarantine in my 55 gallon community tank and my puffers got ich. Easier to treat a 55 than a 230 gallon. I now have my 25 gallon tank with a goldfish and a pleco to serve as my quarantine/hospital tank.....BTW the puffers got better. If I'd added him to the 230 with the troubles I'm having now it would have been a complete disaster. Check out my thread "4 DEAD" and you'll see why you need to quarantine. It may not always be 100% guarantee that you won't get disease, because parasites can live in a fish for a lot more than 3 or 4 weeks before any obvious symptoms show, but it will give you a chance to acclimate the fish to your water and could ,potentially, save you from some ailments. That said ,you can quarantine a fish that may have a parasite you don't see and add him to your tank then the following can still happen:
1) The fish in the new tank stress him out causing the disease to rear its ugly head.
2) He carries the disease to your tank and , even though he's immune to it, your stock isn't and they get the disease.
Unless you medicate for everything under the sun you'll never be guaranteed of anything, but you do limit your risks.
