Still no luck. I *really* thought he would eat last night, he was so active. Nope. So, I did a tank cleaning and did a bedding switch - went from aspen to newspaper.

He is down 0.2lb since I got him. He was NOT happy about being moved. I am lucky - he would rather get away than try to strike.

If he is actove again in the next couple days, I will try a mouse scented with hamster bedding to see if that works (I don't have access to gerbil bedding).
