How to best observe Ts?

I'd like to watch my A. Versi spin but she stops whatever she's doing when I appear I've heared that they can't see red light but I'm not buying that so easily. I put a red plastic thing over my flashlight and I think it still disturbs her. Is there any better way? I wouldn't like to buy night vision goggles

How to best observe Ts? Well, I like the apochromatic refracting scope, with a 45 degree erecting prism. 70mm aperture ought to be plenty. A short focal length will give you a better apparant field of view. Any magnification greater than 25x is probably overkill.

You meant in at home... in an enclosurre, right?

Maybe you're making too much noise when you approach?

i dunno...my A. seemani hunts a lot differently when i feed it in the dark with a red light than when i do with the lights on. Slowly stalks the crickets...creeping forward a bit at a time...in the regular light it just stays in it's hide (cup) til one comes close enough and grabs it. So i'm inclined to believe they can't see the red light. I have mine in a lamp indirectly overhead...
