The perfect alternative to frozen and live feeds:
Tetra's gel feeds
As Dr Hubert Kürzinger, Head of the Global Research and Development department for Tetra food products, explains, "there's no doubt that frozen and live foods are real delicacies for fish. However, using frozen and live foods as fish feed can be problematic. For instance, these so-called valuable foods lack essential nutrients such as minerals (major and trace elements) and vitamins. They are also inadequate in terms of their protein and fat content." Additionally, the feed animals often add pathogens, heavy metals or other impurities to the aquarium water, which compromise water quality and can seriously endanger the fish stock. Also, not every aquarist (or their partner) wants to store frozen and live feeds in their fridge or freezer next to vegetables and cheese.
