Experienced Yellow Anaconda keepers (Questions)

[Tawu]

By experienced I mean people that have owned this gorgeous specie, you don't need to be a sage

I already asked about Yellow anaconda on a finnish forum but all i could get was info I already knew and had found it by myself from google (even though I particularly asked for people that had own experience of the snake). No people that had own experience of yellow anacondas answered... So I figured I could find few here

My bf have been wanting a yellow anaconda for almost a year now and when we saw a few of them in reptile zoo, he kinda totally fell in love We have read about the yellow anaconda on different sites but it seems that the info on those sites is quite variable (especially about the size and temperament). So I thought hearing about personal experience of your yellow anacondas would help.

1. On some sites it says that the average size is about 9 - 13 ft on both genders, but here I read that average size is 6ft - 8ft on males and 8-10ft on females. Of course some inviduals might grow even bigger. So the question is, how big your snakes have got?
2. Growth rate. How quickly they have reached, let's say 8 feet?
3. We have been thinking of building a terrarium that's size would be about 6ft x 3 - 4ft if/when we get a yellow anaconda male. Does it sound too small? Height of the terrarium would be about 4 - 5 ft.
4. The only thing that keeps me from letting my bf have the snake is it's possible aggression. I have read that yellow anacondas can be very unpredictable and feisty. What have your yellow anacondas been like? And how well it can be avoided by proper and regular handling?

Thanks
