new tank questions (plants)

[Robo-snickers]

so i have 10 gallon tank, had for about 3 onths. had a rough start but seems things are starting to settle off and going well. i want to upgrade so i bought a 29 gallon starter tank 2 weeks ago. I got the "Marineland LED Bio wheel one" because it was on sale and looked real nice. its currently cycling. i dont know what the stats are for the tank yet since i havent got my tester kit in the mail yet, but i dont plan on putting fish in it until its cycled. anyways i did research after i bought the tank and found out the LED is bad for plants, and i will be limited on low light level plants which is fine i like anibias and java ferns...think they look nice. i actually have an anubias plant in my 10 gallon now, bought it as at tube in petco, and i was sad when at first i thought the plant was going to die, but a few weeks later its doing amazing. Grown big, lots of leaves, really green. I did notice long green stem like things coming from a few of the branchs from my plants, i have no idea what those are. Im assuming those are "rhizome" roots since they are pointing down towards the gravel. so can i break part of my plant off and re plant those rhizome in my new tank? my new tank is sand and not gravel. and i heard you can attach them to wood and rocks. how do you do this, i want to make sure i do this right o mistakes. and besides anubias and java ferns, what other plants would do well in my tank? thank you.

Yes, and they do need to be afixed to a piece of wood (best) or a large enough rock. Don't bury them in the sand. Using thread should work. Don't ever use wire (that is, copper.)
