During colder periods, the nutritional requirements of fish change slightly. In order to meet these needs, Tetra have developed Tetrapond Whetagerm Sticks for all pond fish. These sticks contain all of the nutritients required by fish during the winter, in a format that is easy to digest, and that will not sit in the gut like non-specialised feeds. By feeding fish during the winter, their energy reserves will not be depleted, and they will start the new season in much better condition.
