I got suction cup holders...like 6 for $2 at my lfs. To hide the tube, I either run it behind a plant or background plant, or you can buy special airline tubing that has plant pieces attached. You simply space the individual plant pieces along the airline tubing and it looks just like a plant. It is super easy to use. I have three of my tube lines that way and it looks really nice. I plan on getting more as soon as my lfs gets more in supply. The others, I run behind a busy plant and anchor both of them to the glass so it doesn't move. It looks nice, and you can't see it unless it gets moved around by the fish. I hope this helps.
