No, all tarantulas are different, and does not matter that they have been classed together, that does not mean they should grow the same and be the same!

But, I would enjoy the spider will you have it, no new spiders have been breed/imported, so when your guys spiders die's that is it for this species in SA, well until someone imports them again or breeds them. Which ever one comes first.

It could also mean you have females!?
