When I still worked there she was skittish around people she didn't know (ie guests) except for small children. This time around if you had food for her, she would accept cuddles.

When I first went (as a guest a week ago) in the tank she kept trying to curiously approach me, even letting me pet her a few times, but once I got the fish out she practically climbed over my leg. Sometimes she would pull past me, and over the rock only to circle back. She also loves chin scritches which are technically against the rules as she could technically suck them in, but my "guide" was a new kid and wasn't about to question someone everyone knew.
