New tank for Mrs pacman

[timscrape]

I just built a new tank for Mrs pacman. It is 18x11x10 not sure of the gallon size. She was in a 25 gallon tank. I have a question. In the larger tank she stayed buried or hidden most of the time. We just put her in her new tank last night. She goes all over the tank, even climbing on top of her hide. Does this mean she is happy or stressing out? She looks happy. Just want to make sure what's going on.

She's probably getting used to the new digs.(Most of the time my 2 pacs are buried) Can we see a picture?
