Well my first idea with the U clips didn't work out. Even with them glued to the tank there was to much of a gap. So I went to Wal-mart to find some plastic report spines and of course they didn't have any. However I did find these things that are almost the same that are for posters. They are black and 24 inches long which is nice for those who have bigger tanks. They are a little pricey at $3 and come two to a pack. They were hanging where they sell the wall posters, you know the ones of twlight, HP, etc.
