night lights?

[bluesox_68]

I've got a question on lighting the terrariums at night. I find that my cresties don't feed as well when the lights are on. I thought that the lights were suppose to simulate the moon creating a more natural enviroment. I have a black light in one and a blue light in the other. Do they see best in pitch black?or is that when the crix come out more? Oh yeah one more question Betty got me hooked on the "secret recipe" and the cresties like it too! lol. But how long until it goes bad?
