okay, this is probably a stupid question but..... I never have dealt with live plants before so I picked up a few low maintenance plants such as anubias and java ferns. I was told these plants prefer to attach to drift wood. As of now I don't have any drift wood in my aquarium. I ordered some driftwood online tonight. For the past week I have just put them in the gravel in my tank, I just put them down far enough to hold them so they don't float to the top. My question is, when I receive the driftwood how do I get them to attach to the driftwood without floating to the top of the aquarium and do they need any special type of food to keep them healthy? and would they be fine if I kept them in the gravel? any information on live plants would be very helpful to me as I know absolutely nothing about caring for them . Thanks!
