Is your tank all ready and cycled? what temperature is it?
as long as it's below 22C then they will be fine in the tank, make sure they have planty of hidey holes as you may find they retreat away for a while whilst they de-stress, there's no need to fridge them unless your tank is too hot.
Good luck, it's very exciting isn't it, I'm sure we would all like to see some piccys once they have settled in. Do you know what colours you are getting? have you thought of names?
Have fun
