Too much space!

[rosebloom63]

My lil bit has recovered nicely, and is eating voraciously again! Since I am home, I decided to move him from the mini tank into the 10 gal (10 long) he seems uncomfortable (like he hid behind his filter for the first night, then crossed the tank to go in the corner behind his plant) so I'm guessing it's a bit much space for him. Any recommendations to fill up some space to make him a bit happier?

You could try some tank decorations, very large rocks (that he can't swallow!). Or give him time to get used to it.
