Sera discus color Red is the color food consisting of carefully Manufactured soft granules for Yellow/Red discus fish. The balanced combination of valuable algae such as haematococcus and spirulina supports the development of this color range in a directed way. Disease resistance, healthy development as well as fertility are enhanced by optimally digestible, aquatic protein, Omega fatty acids, minerals and trace elements. When moist, the sinking granules quickly become smooth without swelling or losing their shape. The water is thus not being polluted.
