I am going to be getting a bristletooth tang and a flame angel in on Tuesday and have established a 10 gallon QT tank. It has all the components that are widely listed for a QT on this forum. Amonia is 0 right now and I have a sechem test in the tank. I also have a lot of bio spira on hand also and already put some in the tank. Everything seems very stable right now. So I read that the angel does not like copper. So if these two come in and I observe nothing on them should I not treat the QT with copper because of the Angel? Should I lower the salinity? I know that keeping salinity stable in a small tank is hard but I spent a lot on the tang and I don't want stupidity to kill it either. Thanks for any help.
