Yep, you can attatch it to driftwood. I use cotton thread to tie it to slatr, untill it attatchs itself. But others use sometype of glue, (I forgot what kind though.) As long as the anubias leaves do not dry out, they can be grown out of water. Does the water fall "splashy?" Also, anubias "petite" is a another option, because it is a short plant.
