Well what's the measurement? I'm hoping for mine to turn out female (doh ) and to grow HUGE, but what's huge talking parahybana? 10"? BTW, mine's the most aggressive T i've ever seen.. lives in a tubething buried in the substrate, usually hangs out with her/his front feet stickin out.. if i so much as look at the area in front of her hole, she starts pounding like mad! formidable spider
