my obt has been in residence for three days and the whole time, she's been on the side of the tank. she walks around near the top feeling the lid. she goes around and around as if she was trying to get out. is she not happy with her environment? i'm using dry coco fiber as bedding and she has a large piece of wood to anchor her web to. she has plenty of water [and has used her water dish several times] sometimes she comes down the side and touches the substrate, but then turns around and goes back up! is this normal? or is she unhappy? is there a substrate she would like better?
