I remember when they were $40 retail.

Not anymore. Now it's $150.
Given that and the rather spotty supply from Mexico it's time to get these guys captive bred.

Juvenile BSJ or Yellow Heads?

KP only sells what they collect most of the time which is yellow heads. They are better looking than their Pearly cousins from the Caribbean Islands. It would be very nice if someone could start raising BSJF babies, many have tried hopefully someone figures it out

I thought that Yellowhead Jawfish is a synonym of Pearly Jawfish.

It is.

Yellow Head Jawfish (O. aurifons) forming pairs that share a burrow is actually atypical for jawfish. All other jawfish I know of live alone in their own burrows with often significant distance between males and females. So I would be hesitant to transfer sex change observations on Yellow Heads straight to other jawfish.

As for breeding BSJ - I don't think their larva are any harder to raise than those of other jawfish. I definitely plan on trying. I got O. randalli to 2 weeks, close to settling down and only failed because I ran out of pods and had to use brine shrimp (which ultimately killed them).

All 3 are still alive and get kind of along. The last one has been banned to a corner near the one of the larger he was fighting with and it seems that they found an agreement. Before they were fighting a little, but aside from a bloody lip on the bigger one no permanent damage was done.
Now it's basically down to the larger one threatening the newcomer. During those displays of superiority the larger one sometimes displays a color scheme close to that of flashing males. So I may very well have two males now.
The brighter colored one of the first larger two is definitely a female and she keeps her distance from the two "males".

I hope I will be done soon with "remodeling" the fish-room so that I can give them a larger tank.

Judging by their behavior I'm now fairly certain that I have two females (the two larger ones) and one male (the smaller one I added later). At this point the small one is certainly the dominant one.

So far they haven't killed each other and despite the usual burrow swapping they kind of get along now.
The brighter colored one of the three is definitely a female and not much involved in the squabbling of the other two.
But with the darker colored two I'm still not sure if they are male or female. The fact that they haven't killed each other yet kind of speaks against both of them being males...
I guess only time will tell.

So, the one I initially thought to be the female is definitely a male. He shows by now the distinct mating coloration.
The one I originally thought to be the male is a female, her fat belly is pretty conclusive.
Only about the smaller one I added later I'm not sure yet. He shows a coloration that is very close to the male mating coloration and is also acting like a male. The only confusing thing is that he by now gets along fairly well with the large male.
