Sure. With very few exceptions I follow this process:
1. Drip acclimate fish
2. Add to QT tank
3. For 3-4 days observe fish and make sure I get it eating well
4. Begin a Cupramine copper treatment
5. After a full Copper treatment for 14 days I add carbon and do a water change to remove copper
6. I FEED my fish Prazi soaked food a few times several days apart.
7. Observe fish for another week or so to see that it continues to eat well and appears healthy
8. Three days before I add it to the display I begin feeding the DT fish more than normal with garlic soaked food to help reduce aggression when I add the new fish.
About a 4-5 week process. FWIW, I have a 40 breeder as my QT. I have PVC pipe pieces, fake plastic plants and a couple pieces of rock for the fish. I also keep a plastic tray of sand in it for wrasses.
