Tetra Pond Sterlet Sticks XL are a high quality complete food specially developed for the nutritional requirements of larger sterlets and sturgeons in garden ponds. The formula contains an optimum protein to fat ratio for healthy growth and a particularly low carbohydrate content for species-appropriate nutrition. Tetra Pond Sterlet Sticks XL sink rapidly in respect to the natural behaviour of bottom-feeding sterlets and sturgeons. The structurally stable sticks do not cloud the water and help maintain water quality by being easy to eat and highly digestible.
