I believe it's a Brazilian Gaint white stripped something or other. Pet store was calling it a Columbian something, but it looks like this Brazilian Gaint one I found online.What kind of a tarantula did you get and what size is it?
I think it's a Brazilian White Knee Tarantula. Pretty sure. The people at the pet store told me it was most likely a female.Yeah...maybe a little more info than 'got her today' would be helpful.
Species and size are good.
How do you know it's a female?
Until then, the generic answer to your generic question is: When she's comfortable.
