standard for them. Mine is the same.
I believe they get around the 6" mark so medium I'd say. Think mine is somewhere between 4-5". Will have to try measuring it soon.My sazimai was in a little glass jar that was about 3 x dls when I got it. Super defensive. I couldn't even open the lid! The spider would climb up onto the lid and stick it's fangs through the airholes!
I rehoused it and now it doesn't even leave its burrow. I think it is about 2.5-3" now and is in it's permanent enclosure. These guys are on the small size correct?
