I would trade it in for another fish.
A sand digging fish digs for food, right? In your new tank, food is scarce in your sand. I don't care for "sand throwing" fish because they disturb the sand bed. A digger/thrower messes up the biofiltration of what little sand bed we have. Compared to the amount of sand bed in the ocean, we don't have enough sand bed anyway.
I recommend a Bicolor Blenny or one of it's cousins as a first fish. They eat algae off the glass and rocks and they have great personality. Like all marine fish, after a while they can become territorial so be sure to use an acclimation container for introducing the next fish and follow the Reefkeeping Tip about adding new fish
