@eatbreakfast has more experience than I with pencils, but I would say that it would be unlikely for a female pencil to transition in your tank. The transitional males can be prone to reverting even if at all dominated by other wrasses. They really do best as the only wrasses in the tank, or alongside only a few other very peaceful species.
Thanks Hunter. I read in your wrasse article that the males are prone to reverting back, which is one reason I don't want to spend double on a male, only for him to turn into a female anyway.
While I have no real aggressive fish, there are quite a few very active busy bodies and a definite hierarchy, with some more dominant than others. Since I don't have much space left, I might rather pass for something more suitable.

But I digress... I bought an orange back not too long ago and at first he was doing great. Never quite as fat as I wanted, but now I'm afraid he is losing even more weight. During feeding he is always out, but is not an aggressive/efficient/fast eater. Lately he has been hiding... nearly all the time minus feeding time. His tail is also a bit frayed. I'm not sure who the bully is- I'm trying to figure that out. I'm also not sure what came first- a bully that made my fish not the healthiest or my fish wasn't in best health to start and for that reason is being bullied (orange back did fine when I had him in my QT and only recently had his tail nipped). In these situations, do you find it best to remove the fish being bullied and put in QT to gain weight/strength or does that add more stress and do more harm than good? I'm trying to figure out who is harassing him and remove the bully (the orange back is my favorite) but so far, I can't tell. Every day I'm more afraid I'll loose him :-/ I can tell he's "not right" but I can't put my finger on why that is. Thanks!
