The photos don't help with sexing your tarantula. A photo more like this
would be more helpful. Less spider, more sex parts, better focus. This pic is of my female GBB when she was much smaller.
Also judging by the photo of your enclosure, you're keeping it too moist for a GBB. Dry substrate and a water dish is all they need, no misting. It's a bit on the large size too. A five gallon tank is plenty of room for an adult GBB.
Well thank you so much for your response. I wasn't aware it was too large, so thank you, I can move it to a smaller one and now have room for a chameleon! As far as the substrate goes, I am aware they prefer drier climates, so to speak, and believe me the substrate is quite, quite dray, the camera may have made the coca fibers look wet because it darkened them. The only area that is wet is around her water dish so as to give her just a wee amount of humidity. I'll try to get better pics too, hard with just a cell though
