Had them before, and yes, they'll be fine as a pair, but probably better off as a school.
My problem with them is their flightiness. The things just go insane over the littlest stuff i.e. a move towards the tank. They're not so bad when the light's on, but when it's not, they just sprint into the nearest aquarium wall. Silly buggers - not very bright.
