Was the question whether or not the male, existing without females, would pulverize the new girls upon them being introduced? I'm interested in finding out as well. My LFS gets gorgeous males in all the time but it's hard to find females.
Out of the 26 I currently have, 2 were male and the rest were female (<2"), and over the past 2 1/2 years, a third have fully changed sex, or started to. And I don't see them stopping anytime soon. Same has held true for the other 3 or 4 species I've kept larger numbers of. P. squamipinnis however, aren't as aggressive as some of the others.
26?! How big is your tank?
