if one gets too large for container it came in, how is it transplanated? currently justin water w/rocks...does it require special rocks? or can it be lifted from container to ampother and just add a few rocks and the water...thanks

You can go move your plant to a bigger sized container if you think it needs the room. You can use marbles, small pebbles or stones, just enough to help stabilize the plant to stay upright, nothing really heavy or they could crush the roots.
