TetraPond Variety Sticks are a mix of three different varieties of food stick which work to keep pond fish healthy. The wheatgerm sticks help fish with digestion, allowing them to utilise nutrients and vitamins more efficiently and floating foodsticks for fish that prefer to feed on the surface, whilst the koi sticks promote general health and vitality and bring out the vibrant natural colour of your koi carp. The feed can be used all year round once the temperature reaches 10 degrees Celsius, and the large bag means you won't run out too quickly.
