Daniella, the fish can become stressed by being placed in a smaall bare tank with nowhere to hide and no other fish to distract all the predators that the new fish is sure are there, just waiting to get it. This can cause stress.
I always add new fish directly to the DT, sometimes there is a bit of chasing, but there are plenty of places to hide and the fish always settles in much quicker than I've seen in QT tanks.
This is my experience and my preference. It's how I've always operated and I've never lost a fish to ich in 14 yrs of keeping saltwater fish. It may not be your preference, but we'll have to just agree to disagree.
Readers can hear my story and your story and decide. You don't need to sell your story so strongly.
I may have ich in my tank, but my fish are healthy and fight it off. Same as my house..I'm sure there are cold and flu virii here, but I don't have a cold or the flu. I can't quarantine any new person or object coming into my house, and surprisingly, nobody in my house is dying. I just added new fish to my tank, no ich, no death, just happy fish.
This works for me and many others. If you have an established QT system, then great, glad that works for you, but it's not what I would do myself.
