Today I will show you how you can use your standard flake food to make an eatable film on aquarium wood, rock and other structures.

You probably already have all the ingredients in your house.

In natural habitats quite a lot of the creatures we keep in our aquariums spend a lot of their time grazing on aufwuch. This adopted German term (meaning ‘surface growth´) is often used to describe the mix of plants, animals and detritus adhering to solid surfaces such as rocks, wood or vegetation in aquatic environments. You can think of it as an eatable biofilm that fish graze on.

Plecos, otocinclus, hill stream loaches and a bunch of other popular aquarium fish do this for a living, literally speaking. As do snails and shrimps. Some of these actually need to digest a bit of wood along with the biofilm.

In this video I use flake food. You can use crushed pellets, mashed green peas, repashy and a lot of other stuff as well.

Try this little DIY tip, and make your plecos, shrimps and other grazers happy.

Thanks for watching :0)
