The only one I know anything about is c. crawshayi. They have needs similar to your h. gigas, and are kind of a pet hole, the way most burrowers are. They live around 15 years or so, assuming you get a female, can throw an impressive threat display, and can stridulate their front legs to hiss (so can h. gigas).


I know that the braunshauseni is supposed to be the largest of the avicularia in the hobby, and are supposed to be more defensive than most of the other avics, in general.
