One of each would be less than ideal IMO, better off to pick one species and get 3-4+ of them.
I have both in my 70g and they seem to be fine with each other. They have all kinds of places to hide and stake out their own territories.
I cannot say what happens during the night of course. But I have not seen either of them to be stressed. They have been together for 4-6 months now. Not sure what long term will look like but they are both fairly large size.
