The idea of potting one and mounting the other is good, too. I was just going to come back and say if they were mine, I'd mount both those little ones on the same mount. They might make a nice specimen plant in a few years.
I am migrating towards mounting my Phals here, frankly. The ones I have in pots seem to all be climbing out and putting roots up into the air, so I think with our high humidity and heat, they like their roots more exposed. Plus of course I do spray them nearly every day if it doesn't rain, so they don't dry out too much.
Becky, I should have said if your orchid lives outdoors I'd go with mounting rather than a pot, but if it's an indoor plant, a pot might be better. You'd not have to water/mist so often. Mine are all outdoors.
