She escaped again, right when I was leaving for work. My girlfriend ran outside to get me just as I was getting in my car. This time catching her wasn't so easy and they were definitely biting at each other. She managed to escape and get under a rock (where I couldn't get her) and hide, my male was on the other side of the tank, he eventually found her and chased her some more while I was frantically trying to net her. The male eventually got her onto the sand bed in a corner by a rock, at first he swam away as I was taking the lid off the tank in an attempt to get her out, but he then started to resume the attack and strike at her as she lay on the sand not even trying to get away at this point. I grabbed my feeding tongs (that I use for flakes (it's fun having all my fish come over and eat off it as I hold the flakes

)) and chased him away. She then came back out and I was finally able to trap her in the net and get her back in the box.
She seems okay, I can't really see much damage (my male definitely has some damage but it's still nothing major and barely there; just a little discoloration on the side of his body that may have already been there), but I did notice that her color was changing while she was in the corner...? Her face began to show thick bright-pink lines (head only) that I definitely didn't notice before, once I got her back in the box they started to fade away... Do wrasses have stress colors? The only fish I own that I've seen able to change colors/markings is my one spot foxface.
Anyway, this time I not only put the floating cover on the breeder box, I also put the net over top of it so there's NO friggen way she can escape again!
I'm starting to believe this may be hopeless as I've read that C. Solorensis generally will not tolerate any other fairy wrasse species (unless you have a giant tank) except for females of the same species (and neither myself or anyone in here is 100% certain that the wrasse in question is a female C. Solorensis (probably about 90-95% sure in general

)). I have noticed that the newer wrasse seems to be getting more gold on it's main body, just like Live Aquaria's pictures of the female C. Solorensis so Evolved may have been correct that it was transitioning to sub-male/male, but it may now be transition back to fully female...?
Guys I need honest opinions: Should I go ahead and get a bigger box tomorrow and wait this out or should I return her? I'm leaving on an international business trip for a week at 10pm on the 11th, my gf and father will be watching/taking care of the tank while I'm gone and I doubt they will know what to do if aggression becomes an issue. This is currently day #3 of the social acclimation (it started around 7pm on Sunday, the 29th)
