So the rest of this post makes sense, here is a picture of my setup:


I have been watching my BP late at night (2-3am) because this is when he is most active, and I have found that he has a strange fascination with the hole in the aluminum foil. I don't know if he is interested in it because its the only open space in the lid, or if it is because he is interested in the black light that sits there. Any ideas? I don't think this is some serious issue, I am just curious about behavior.
