No I didn't glue her foot! She can move a little if she wants. But the sides are slightly raised so she can't scoot off. I kept seeing her foot coming out while she was on the LR but the bristle worms seemed to be irritating it and so she'd retract it. Hopefully this will end that issue I don't want her on the SB because I'm not comfortable with her getting enough light down there. She's doing really good where she's at and I'm already seeing new growth on her shell
