I have a BTA that I bought 3 weeks ago. The first night I stayed in a small cave. The next morning he moved and after searching a moving lr's I found it on the roof of another cave and that's where it has stayed since. My question is "Don't they need light?" I can't see it getting any where it's at. My clowns will go up into the cave and they seem to host with it, I can't really see if they are though. I tried aiming a PH into it, but no success there being the caves entrance is lower than I can aim the PH and not stir up the sand. Any ideas on getting it to relocate? Or just hope it will move on it's own or how to get it to let go without harm, because I could close up the cave for awhile if it came out. Jeff
