JBL ProNovo Fantail Grano S is a granulated staple food size S for veiltails and other goldfish breeds from 3-10 cm. Goldfish - the most popular ornamental fish of all! About 1000 years ago, the beautiful colours were bred out of crucian carps (cold-water fish) in China and the goldfish was created, complete with its own scientific name (Carassius auratus). In Japan, the shubunkin form was cultivated around 1900. Goldfish and related breeding forms such as veiltails, shubunkins, comets, orandas, lionheads, red cap goldfish and others have no stomach and are omnivores that can develop a healthy appetite for aquatic plants. Unlike the common goldfish, the bred forms are often more or less restricted in the way they swim. As a result, their food intake is somewhat slower.JBL ProNovo Fantail Grano S+ prebiotic & sinking food for goldfish breeds: dedicated dietary fibres in the food supply the beneficial intestinal bacteria with food for a healthy digestion+ natural raw ingredients without
