sera Viformo is the staple food consisting of carefully manufactured tablets for catfish and other bottom oriented fish that look for food on the ground. The nutritious and easily digestible food is characterized by very high acceptance. The balanced composition enriched with Gammarus and algae supports the healthy development and liveliness of the animals. The appropriate nutrition of fish with a small mouth (e.g. armored catfish or loaches) is ensured as the sinking tabs fall apart into mouth sized chunks when the fish search for food at the bottom. The food chunks remain compact and do not cloud the water.
