My G. rosea female that I purchased 2 months ago is behaving very strangely. Normally she just sits in her cage like a rock, unless I'm feeding her, but other than that she moves very little. A few days ago I went to see her temperment with a paintbrush as I always do before handling her, and instead of moving forward a little she spun around and attacked the brush. Since then she has become increasingly skittish, to the point were today she jumps when I shut the door 12 feet away from her and leaps forward with her fangs out when I turn the kritter keeper to see if anything is wrong. She's never done anything like this since I've had her, anyone ever had this happen before or know what it might be?
