Hi I have a few questions about my whites. I purchased them both the same day and assumed they were the same age. Well one of them is huge and I'm guessing it's a male because he started croaking and his throat puffs up. The other is tiny, it hasn't grown much since I had it. And I also don't no wether it a male or female. I will be going home to look at her thumbs soon. So one question is aren't the females suppose to be bigger then the males? Why isn't the other one growing. I also would like to know if you can tell there age by there size. I'm going to try and uploa a pic. Thank you for the possible help.
