Banded Trochus Snail - Trochus spp.

The Banded Trochus Snail, Trochus spp., is a hardy and efficient algae grazer prized for its ability to consume film algae, diatoms, and cyanobacteria without harming corals. Known for its distinct banded spiral shell and ability to right itself if overturned, it is one of the most reliable and reef-safe snails for cleanup crews.

Additional Tips:

• Algae Control: Consumes film algae, diatoms, and nuisance algae on rocks and glass.

• Unique Advantage: One of the few snails that can right itself if overturned, making it more resilient than many other grazers. They're also unique in their ability to readily breed in captivity due to their short planktonic stage.
