About Giant Nodulose Creeper
Large cerith snail and one of the most underrated cleanup-crew members — it works the sand bed, the glass, and rockwork equally, eating detritus and film algae. Stack a few in mid-sized reefs and forget about them.
Cerithium nodulosum is a species of sea snail, a marine gastropod mollusk in the family Cerithiidae.

Sourcing and feeding. Wild-collected from Indo-Pacific reefs; available through reef cleanup suppliers ($5–10 each). Detritivore — algae, leftover food, detritus.
