I'll remove moss, and the mold was a fuzzy white color. It looked like cotton almost. And as for the crickets, the pet store lady told me they fed him large crickets and he accepted them no problem. There was even one large cricket left in his tank after she said she fed him 5 and he ate 4.

And the the water is spring water from a plastic gallon. It's distilled. Non chlorinated and contains no heavy metals.

You say the ceramic heat emitter dries the air a lot, yet the moss is what keeps the humidity in. How can I keep in humidity if I must remove the moss?

Is a 60w red nightlight bulb the same thing as a 60w infrared bulb?
