Tetra Pond Holiday consists of natural food in a vitamin-enriched gel. This means it is 100% edible and provides superior nutrition compared to traditional plaster-based holiday foods. Another advantage over
plaster-based foods is that there is no alteration of water chemistry.
Tetra by the way are the worlds foremost fish food and pharmaceutical company and always a name to trust.
