I've got a vulpinus, ordered it from Darrin Vernier back in April. I think it was 3/4 inch at that time, is now 4" +. They grow very fast, and mine is a little skittish, but not very bitey; likes to kick hairs though. They look a little drab up to about 4", in my view, but once it got some size and some hairyness going, it is quite pretty. Color is more like a strawberry blond than straight blond, quite a few red-orange highlights, very pretty, and eats like a horse.
Vulpes in Latin means "fox". Vulpine therefore means "fox-like". (Same as lupine, canine, feline, and so forth.) I have no idea what this means in context with the tarantula, just thought I'd throw that out there. You probably already knew that. I'm just gonna shut up and watch now. :8o
