Most loricariids and many other fish eat aufwuchs.

Aufwuchs is a loanword from German language and means something like overgrowth.

It describes a conglomeration of herbal and animal organisms which form a living film on stones, rocks, wood, roots and any substrate.

It is a species community of algae, bacteria, crustaceans, worms, insect larvae and different microorganisms.

This living ensemble is nourishment for many species.

Discusfood developed a new kind of fish feed especially for plecos and other bottom fish.
