I got my aquarium plants but they are just stems, no roots. How do I plant them? Do I leave the twist tie thing on the bottoms (they are bunched plants) or take it off? Just stick the stems into the gravel? Hurry I don't want them to dry out! 
ETA: ok I did some searches and found out how to plant the plants. Now what? It looks horrible in there-leaves and pieces of plant floating, all clogging the suck tube of my filter. Is that normal? Do I need to get that stuff out somehow?? I think I just have too many in there-I need to get my 2nd tank set up and put some in it. This tank is a 20 long and I think there are 10 plants-5 of them hygrophilia and 5 hornwort. Is that too many?? (they were on sale
