Can they change ---? I bought a female about a year ago, and the past week or so her (his?) tail fin has been getting a brighter and brighter yellow. I am noticing that her top and bottom (very technical I know, heh) fins, are starting to get yellower to. The blue on her jaw is also becoming more pronounced. Any clue?

I am not the person to ask about regarding specifics on them, however, mine is great! Comes up to my face when I go to the tank, and eats krill from my hand. Very docile to, except when the Blue Damsel gets outta line.
I feed her/him mysis/brine w/ garlic and Vit. C every day, and krill every other day. It also LOVES lettuce. I put it in there for the foxface and it eats more than her share, which I always thought was weird, but whatever...
here is a couple shots...

I will difur to someone else for a definite answer, but from what I have read on here, I think you should be fine. (With caution on your CUC.)

I originally had heard it was possible for Xanthichthys family Triggers to change ---...I recently read on Wetwebmedia from Bob Fenner that it is in fact not possible, or at least to his knowledge. Bob knows fish.
I think male Crosshatch and Bluejaw take awhile to develop their "male" coloration.

Wow, cool! Thanks alot. He must just be "slow"...
Truefishman - The color is actually a bright yellow, the photo above doesn't show the colors well. It does look orange in the picture.

My female blue jaw did in fact turn into a male. Please pick up a copy of the Jan/Feb issue of CORALS. It has 10 pages devoted to triggers and including changing sexes in an aquarium setting. It has not been noted in the ocean as no one as choosen a specific pair/individuals to track over years.

My understanding is they do not "change s ex", they are undetermined until a certain size and then become that s ex. Again, it is not possible (in my understanding) to tell them apart until they reach a certain size. Sorry Smalltriggers but as we noted, yours was always a Male. No offense to "Coral Magazine", but I will take Bob Fenner and Wetwebmedia over them any day..Here is the letter to Bob
Hi WWM, I am writing to ask about the chances of --- change in Bluethroat Trigger...
<Just saw a nice male yesterday... diving at the end of the Old Airport Rd. north of Kona... Sabrina and I (and the Russells today) are visiting out in Hawai'i>
Do you have any idea whether will they go through --- change like Clownfish and Anthias if there is two of the same ---... Or they don't experience --- change...
<As far as am aware tetraodontiform fishes don't change ---... may be "juvenile colored/marked", and just "changing" into their/its determinate --->
I have two male Bluethroat with me now... No aggression so far, so if they are able to change ---... I would just leave them alone... Would there be any long term problem if there are two males...
<Likely so... better to separate, trade one in>
Thanks in advance..
<Welcome. Bob Fenner>

but as you and BOB FENNER stated, hes never noted it, that doesnt mean it doesnt happen. The author of the articles in CORAL has noted it and documented it. Not only with blue jaws but also crosshatch which are born with their gender specific coloration just like blue jaws. Females are born with female coloration and so are males, they may get brighter or darker but they do not change colors; unless they change gender. Please feel free to assume you know that my blue jaw was a male to start with, i have had that fish in my possesion for almost 3 years, i would have noticed if it were a male to start with.
Bob Fenner is a great man, but as he has stated many times, he does not attest to know everything about saltwater fish. And I am just letting you know what I know which was in fact validated by a specific article in a well know magazine. Take it for what you want, and feel free to read the 10 pages about triggerfish in that magazine. It def. has more information i could have possibly attained in my 7 years of studying this hobby.

There is no way to actually know with out physically sexing the fish weather or not it is/was a male or female. could just be that the share very similar colorings until they reach sexual maturity. Most fish that are can change do so based on need such as a clown fish. If you take three juvenile clown fish and put each in their own tank then you would end up with three females, however if you put those three same juvenile clowns in the same tank you would end up with two males and one female. Using this knowledge one would think that if these triggers had the ability to change then all bluethroats not kept in pairs should turn into males. This is not even bringing up the fact that all of the fish that I am aware of that are KNOWN to change live in harems which to the best of my knowledge bluethroats do not. Not saying your right, not saying your wrong just imputing the very limited knowledge I have on the subject

How is it that you're assuming your's was a female to start with? In your thread, the first pic you posted, you can clearly see blue on the jaw. Female Blue Jaws do not have any blue what so ever.

Exactly....The before and after pics you posted were both males

Just wanted to point out that BrianBeme posted those pics.
In regards to Bob Fenner, he does indeed know his stuff but I have seen contradicting information to some of writing. Fish don't read these books.
