Well I keep mine close to freezing for the winter (dark) then when spring pops up (around january/fe/march) they are setup in a tank which very high humidity and water. I kept 5 in a tank of 60 by 40 which did well, but I am using those stones / buidling bricks with isolation holes in which they hide.
They were again succesfully bred through a friend of mine (who has offspring of mine) so we are (both) currently at F2.
Mine are form the Portland, Oregon region and are nominate subspecies (A. m. macrodactylum).
