I got her yesterday and she has already attached to rock. The rock is actually in the area of the tank that I want her in. Here's my question she has wiggled around today to where she is only a few inches from my feather duster. Is this a huge problem? Will the RBTA hurt the feather duster? I really don't want to move the RBTA since she is fully opened up and is in a perfect spot. I don't want to move the feather duster either since he is attached to. Thanks in advance for any help.
