Thank you Adam!

adi, it really depends on what you feed it, whether it decides it wants to go off feed for a while... That spider has gained 220 grams in two months. My son's spider has lost weight in about that same time span. Make sure that you are feeding appropriate sized prey (roughly the same thickness as the snake, or slightly less), and you'll probably want to switch it to rats as soon as you can (assuming you're feeding it mice). As far as average annual growth, Adam is probably your best source for that answer!
