JBL ProNovo Tab M are food tablets for all aquarium fish from 1-20 cm length. Bottom-dwelling fish tend to seek their food at the bottom and so sinking food tablets are ideal for them. Sinking granulate food for the other fish will also reach the bottom, but really only if too much has been fed! It therefore is useful to feed the free-swimming and bottom-dwelling fish species separately.Almost all bottom-dwelling fish species eat JBL PRONOVO TAB. But even the free-swimming fish species quickly learn by smell that the tablet consists of food. Very large fish eat them whole, smaller ones bite off. Once the tablet sticks to the glass, all the fish enjoy eating it and its great fun to watch. JBL ProNovo Tab M+ ideal for all bottom-dwelling fish species and also all others when the tablet is attached to the pane+ use: either let it sink to the bottom of the aquarium or attach it to the aquarium glass with light pressure from the inside+ natural raw ingredients without artificial additives
