Algea eater name starting with F

We have a tank in our office with a small snake like sucker fish, but nobody can remember the name. It is about 6" long, and slightly rounder than a pencil.
The name if we recall started with the letter F. Everyone keeps saying Farallower (or many variations of this), but we cannot seem to find what exactly the fish is on the internet.

The reason I am asking, as this fish has made a great companion for the Pleco.

Thank you,
