Red Light

I find an undersized blue light works best for nighttime viewing.

Whether or not you use a red light, he'll still sleep during the day. I've heard various thoughts on the colour of light and what colours amphibians are more sensitive to. I believe they can see red light, but they seem to find it a little less shocking at night than red tinted light.

If you want to light your terrarium at night, I agree with Johnny - what he's describing is a "moon" light.
