How does the magma and flame get along? I have a magma in my tank right now only because my LFS called me telling me he got some nice wrasse in (put a huge dent in my wallet). My plan was to always have a flame wrasse pair in my tank.
They are fine. The flame was a little defensive at first in QT but they got along fine after a day or two. Now in the display, they sometimes swim together and other times they'll do their own things but freely tolerate each other.
I wouldn't bother with a pair, the live in harems in the wild. So the pairing is unnatural to them and eventually the female will go male and you'll have a war between the two male flame wrasses.
Here's Evolved's chart on fairy wrasse groups and compatibility.
