1.) What temp should it be at day/night time for an emperor scorpion?
26 or 28 degrees i guess, just put a heat mat on the back
2.) Whats the best way to keep up the humidity? do u need to buy a humidity gauge?
no you dont need a humidity gauge, they are useless. just pour water onto the (cocofibre) substrate when it looks like its a little bit dry
3.) Whats the best way to identify which scorpion is male or female?
show us a picture of the underside of both scorpions and we can tell you which is which
4.) Should u handle the scorpions the for the first few days or let them be?
5.) Best way to handle a scorpion? I've seen guys at the pet shop pick it up by its stinger is that a good or bad way to handle?
dont handle the scorpion unless you really have to. i coax them into a tub with a lid if i need to move them. handling a scorpion stresses it out, increases the chance of you getting a pinch or sting, and you might drop it (well, it might let go) which is likely to kill it.
dont do it.
