I would definetly quarantine any fish that came from a store, unless they specialy kept the fish for me for at least 3 weeks in a tank with copper and I also 100% trusted the guy selling me the fish.
I quaratine for 6 weeks no matter if it came from a LFS or someone else tank. I have too much $ in my display tank to risk an infection. It is also a PITA to try to remove all the fish to the Q-tank after the infection is notice and must rip apart all the live rock and corals to get all the fish out. Lot simpler to Quarantine for 6 weeks and know your fish is clean and ready to go into the display tank. Its easier to observe the fish in the Q-tank also.
I just bought a Naso and Powderblue Tang and it is in Quaratine for another 5 weeks. I know its tempting to just put them in the Display tank right away they are healthy and show no signs of disease!
Remember the fish might look healthy, but still carry a disease sometimes!
I was impatient awhile back and quaratine a Powerbrown Tang only for 4 weeks and it infected my tank and lost $200 in fish in a week.
I always add copper and maracyn in the Q-tank when quaratineing fish
To reduce stress on your new fish, quarantine them for 5 to 6 weeks under normal water conditions, no medicines. If any symptoms develop, treat accordingly, and start the QT period count-down from when you stop treatment.
I run the copper for a month as the direction in coppersafe, one dose is good for a month.
This is my method of quaratine i have always used and others might do different.
Answer this question to yourself: How many other fish were put in and taken out of the same tank that fish is in that you've been eyeing for the last couple of weeks and how many of those fish that have gone through that same tank had diseases that you won't even notice until you take said fish home and put it in with all of your other beautiful and expensive fish in your massive system with all the live rock and coral that you will have to tear down in a couple of weeks because that one disease showed itself after that beautiful fish was put in without QT?
In my area one lfs says they use copper in their 20 gal holding tanks and another lfs drops their salinity to 1.018 in their holding tanks to reduce diseases! I still quarantine when I buy from them.
Like Freed said how many fish went through the tanks with diseases unseen to the eye.
Perfect example I am quaratine a PowderBluue Tang as we speak and it looked in perfect condition when I purchase it a week ago, beautiful colurs, fat and healthy. But 2 days ago it developed a white film on its right eye and got worst. I treated with Maroxy so far 2 doses and the eye clear up and will treat 3 more doses as directed.
Good going PowderBlue. Perfect example of why QT is so necessary. I had a CBB and a six line wrasse in QT from the start on Feb. 10 and although they looked like they had no diseases whatsoever when I bought them (they were in a tank that was plumbed in line with dozens of other systems in which some of the fish looked terrible) I knew I was in for a long haul with these two because I knew what the other fish looked like that were in the other tanks. So the water they were in was teeming with all the diseases that the other fish had. After a few days in QT I noticed ich on both of them and treated with Hypo from there. The ich died and now they are in their 75 gallon living very happily. Key word being LIVING thanks to QT in my 20 gallon.
No LR, just lights, heater, oversized skimmer, but oversized is not necessary unless you have more than a few things in QT at once, and oversize canister filter, again not necessary. I would just rather over do it than under do it.
OK, let me ask my question differently. The LFS has a yellow tang they have had for over 2 months. Its in a tank they run copper in. Why is it better to bring that fish home and put it in a new (unaged) enviroment with no live rock to graze and the tank itself is to small for a tang anyway? Looks to me like that would stress the fish out enough to make it sick? Then, move it again (more stress in a month). Basically it has been quarantined at the LFS hasn't it? If its been in copper for 2 months, why would it come home and break out in my tank all the sudden? PLease explain this to me, b/c common sense is telling me the least amount of stress to the new fish in this situation is to put it straight into its new home, thats appropriate for its size and has a natural live rock to graze on enviroment.
So you're saying bring it home and throw it in with a bunch of other fish that want to pester the he!! out of it because it's an invader even though it has supposedly been in a tank for two months with God only knows what strength of copper that has been monitored only on a semi weekly basis probably no doubt and with the possibility that just yesterday a bunch of fish went through that same tank that had too many diseases to count. Does this sound safe to you? Only you can answer that question.
wow you seem angry, lol. I think a lot of what you just said automatically assumes the worst of the fish store. Also, I don't understand even if the fish is quarantined it would eventually have to go into the new tank where the fish want to pester the hell out of it?
any time you move a fish you put stress on it.you should q a fish for diseases,and to build up its strength by letting it eat with out any of the tank mates picking on it.
Robin, please don't read any emotions into a post. There are none there. You're not listening to what is being said. It's a question you need to ask yourself and try to understand. If you do then you will understand what is being said.
