I can't decide which species to get. Although they are amazing, I don't want a female green - they are just too big for me right now.

Can someone with more experience than me help me out? I am debating between a female yellow or a male green. What are the temperament and size differences between the two? I had been leaning toward a female yellow but the greens are just so beautiful. I have heard yellows are a little more temperamental and get a little larger than the male greens.

Any input would be appreicated!
