After almost 3 years of unsuccessful attempts to capture my six-line, he finally passed on. This has opened the door for me to pursue other wrasses. Using Evolved's chart I have come up with a stocking plan but I want to make sure that it has a good chance of working.
C. Jordani (Flame)
C. Isosceles (Pintail) or C. Lunatus
C. Beauperri (Beau's)
C. Aurantidorsalis (Orangeback)
P. Mccoskeri (McCosker's flasher)
If this list is ok, do I need to add them all at once? Should I add the Orangeback last since he may be the most aggressive? Can I just add them as they become available?
The C. beauperri is the only one on your list I haven't kept so I can't speak to him but otherwise those would be great. I would add the C. isoscoles and the flasher first because they are smaller and in the isocoles case more demure. Then maybe the flame and Beau's and finally the Orangeback.
I would also encourage you to think about adding a second or even third flasher. The interaction and flashing that ensues is really cool to watch.
