Catfish and especially Plecos need a different diet. Cellulose is a part of that diet in the wild as they feed off the roots and branches of dead and live trees and shrubs. To provide those nutrients in an aquarium we added cellulose in the form of Stinging Nettle. Just enough to provide what is needed.

We also made the wafer hard and with some weight to encourage the natural scraping habits found in the wild. As these fish are nocturnal, most of the feeding is at night, so this pellet will hold up for hours in the tank and will not foul the water.
