Nothing goes in my tanks without quarantining first. Aside from the fact of introducing nasties into the DT, I think it's important to acclimate new fish without the stress of competition. I have a 33g with a 20g sump with skimmer, lighting, PH's etc. I use it for a frag tank and QT. I can observe the new livestock and fatten them up before going to the DT. If I need to medicate I have a spare 20g ready to go. It might be a little more expensive set up than most but I feel it's necessary and it works for me.
