plastic rock

  1. Can I attatch Java moss or Java fern to a plastic rock formation?

    This is the tank decoration I have gotten from petsmart. It's a large cave, made of plastic. There is a fairly flatish surface on top on which I would like to try and grow either javafern or javamoss. Would this be possible? Inside the red lines is where I would like to place the moss and get it...
