sera Guppy Gran Nature Veggie food consisting of slowly sinking soft granules sera Guppy Gran Nature is the veggie food consisting of gently manufactured soft granules without dyes and preservatives for all herbivorous fish that mainly eat in the middle water layers, such as guppies. The carefully selected ingredients, such as 4% natural spirulina, support healthy digestion and liveliness. The easily digestible composition rich in energy optimally fulfills the requirements of guppies and other particularly active fish. The soft, fine granules sink only slowly and become smooth in water, but also keep their shape very well and do not affect water quality.
