Any of the Pocilotheria are stunningly beautiful, but they are very fast and pretty aggressive.. My spiderling escaped while I was feeding it. Luckily I found it. And being a rarer species, expect to pay between $150 for an usexed spiderling to $800+ for an adult female. I have been keeping tarantulas for 10 years; this is one of my favs, but do start docile.
