I am really torn with how to respond to these threads. I do own a 'few' jobiensis, and they are one of my favorite species.
I could tell you exactly what most books say, which in my opinion are complete misconceptions based off of stressed imports that have not become used to captivity.
I could tell you the truth, but then you will get an import, kill it, or grow tired of it treating you like satan and sell it in six months and call me a liar.
And no, they aren't just a bit bigger than ackies, males often exceed 3ft TL. A 4ft male peachthroat is not unheard of in captivity. Temperment wise, I find them to be very similiar to argus in many ways, including feeding response.
This is nothing against you, or the other people asking for very generic things about species. Opinions are all a matter of perspective. Personally, I feel if you have to ask (and the opinions are important to you) about this species, you are not ready for them. My opinion will not make you feel better, when you have had a lizard for many months, it hasn't eaten in weeks, and you never see it. You have to have a certain dedication to stick with things no matter how bad they get, to really appreciate this species.
If you want an opinion get something c.b., crosses (gouldii complex), ackies, etc. avoid the w.c. indo species.
