My new 210 gallon tank (7'X2'X2') is currently cycling. I have 30 gallon QT tank that is now done cycling and I want to put my Bellus Angel in to start the process. I have had her about a year, but she has spent the last two months at my LFS being held for me once I sold my previous 125 gallon. My plan is to do a round of Prazi first and then Cupramine. This is my first time QTing a fish and wanted to get thoughts on if both meds are needed and if there is anything else I should know about QTing this fish or anything in general. Could I add another fish in with the Bellus? She is about 3 inches. My LFS has a Sunset Butterfly (Chaetodon pelewensis) that I would like to get, it is about 3 inches as well. Thanks for your input!
