Congrats Wayne! the beautiful thing about these fish are that they will adapt quite well once acclimated. I know how you feel with your nerves. When my 3" Consipic arrived I was on edge for at least a week.
Here are a few quick tips on getting her to eat almost immediately.
Freeze a fresh clam then use a cheese grater (the small holes) and grate it up into a fine mush. Feed a small chunk 2 times a day. The smell and the tiny pieces of meat will be irresistible to the fish...I bet it eats within minutes of the food entering...
Good luck...she is a beaut!
