I've never seen a G. rosea sold as a "Chilean Fire tarantula", and this does NOT look like a Rosehair. "Chilean Fire" is the pet trade name of what's known as Euathlus sp. "flame", though this actually looks more like a closely-related, and possibly conspecific, E. sp. "yellow". You can check out this thread and scroll down a bit to see pics of both for comparison, but I've certainly never see a G. rosea OR a G. aureostriata with that bright yellow at the conjuncture of the abdomen.
