just picked these guys up from josh's frogs. IMO zach (from josh's frogs) is probably one of the best in the business. if you ever look into getting some frogs he is the man to speak 2.
i have a set up that has been going for a few months now. i really wanted the springtails to get established before i put any frogs in. so i might keep them in a temp set up until they take off.
