Thanks, I appreciate it. Personally, I would set up the 40g breeder and get a 10g in addition. Use the 10g to acclimate/medicate/copper then transfer them to the 40g for additional observation. The small volume of the 10g allows you to use less salt and meds to treat and raise salinity. Use the larger 40g to reduce stress, improve feeding, and give an additional observation period prior to putting them in the DT. As I tried to point out in my article, what I lay out here is really intended for people new to the hobby with smaller tanks. This is an absolute bare minimum that I would recommend. Since you have the 40g already, and don't mind getting a 10g, I would do more than the bare minimum.
