Petco in Mansfield had Tuxedos and a couple spiny urchins 2 days ago. I know Petco isn't most reefers choice, but this location is decent. The woman that oversees it was in the Norwood store before it closed and been giving good advice for 4 years. She makes the place acceptable and keeps decent inventory. That being said, All Things Aquatic would be my first stop, but at least there's a second place a couple minutes away if Kevin is out of stock. Good luck!
