@ Jeff K: Thanks for the offer, but to save the trouble for you (and $ for me^^) I can probably make a quick trip to the local OSH to get a piece if in fact I do need one. But I do like the black film that you have on your tank, I need it for my leo gecko. And I to plan carefully because right now I have an empty tank... I am eyeing on the pyxie or the crested gecko... I heard that the pyxie frog are really entertaining to watch when it comes to feeding, is that true??? How are they different VS the pacmans??
