Just a quick anecdotal story.  I have had a win spot (my daughter named him Spotsy-Jumpy) in my 135 gallon for just under a year now.  Spotsy-Jumpy was added when the tank was about 6 months old as I wanted to more certain in his food source.  He has not been paired up all that time and he has never once shown signs of distress.  Nor do I do anything special for his diet, but then again he has a very large dinner plate.  Maybe I got lucky, I don't know, but I would not rate them as high as ten out of ten for difficulty of care. 
 
Although it does sound like you may have some difficulty with the move.  Good luck.
