Again...the weird thing...and this may be of interest to you Richard...is that my snow, Possum seems to like light...whereas my albino checkered, Hermes, reacts like most albinos....he hides from it and acts as though it bothers his eyes. I am wondering why it doesn't bother Possum. Now, of course...I am not shining UV light in Possum's eyes or taking him out into direct sunlight...but Hermes will hide from most light if it is too bright. Possum seems to like a certain amount of light...he seems to require it in order to be active.
