Do you have additional lighting in the vivarium? You want to try and simulate tropical conditions for the Red Eyes which includes a 12 hour photo period daily. Your Pothos needs this light also. Those spiral bulbs are fine but need to be on more than the few minutes that you are viewing. The best of course is a full spectrum light. For night viewing of my Black Eyes I only use two 12 volt LEDs, one on each end of a 50g to give just enough light to see them in the shadows. They are nocturnal hunters and need it dark to see well. If the blue light puts out more than a very soft glow I wouldn't use it.
