You have such an odd snake getting into every possible crack and crevice.

I was going to suggest silicone to secure that down but what if you want to clean it?

How about velcro instead? You could always either silicone or super glue velcro to the fascade and glass but you would need some place to keep the snake while it sets.

If cleaning isn't an issue then why not just silicone it to the wall?
