DezB the male is slightly bigger and about 4.5-5cm long and I'm guessing 8-10cm wide, but that depends if it is laying flat or standing up. They are quite fast but very easy to look after.

Arachnids don't know as their enclosure is emulating their natural habitat and these are captive breed. However they won't get eaten, starve, diseases or dehydration and they don't have mites. Also as not so fluffy animals are often ignored when it comes protection understanding how and where they live will also improve their chances when it comes to protecting their natural habitat.
