Is there shell fragments anywhere? If not, the snails may be hidden in the rocks.
FishBase states that while this species does feed heavily on algae, they will also feed on small benthic invertebrates, including molluscs and even hard corals (most likely SPS; most tetraodonts can use Acropora to grind their teeth). Perhaps yours has aquired a taste for your snails.
