Pond fish don't stop needing to eat in winter, they just need a different kind of food for it — cold water slows a fish's digestion right down, which is why a food built for autumn and spring earns its place next to a summer one rather than replacing it.

These are wheatgerm-based sticks for pond fish, built around 28.4% wheat germ meal alongside vegetable protein extracts, cereals, yeasts, algae, oils and fats and minerals, and formulated specifically for use when water temperature drops below 10°C. This listing covers more than one pack size.

• Protein 33%, fat 5.5%
• Fibre 2%, moisture 8%
• Wheat germ meal makes up 28.4% of the recipe
• Vitamin D3 at 1730 IU/kg, citric acid at 274 mg/kg
• Feed 2–3 times a day, only as much as fish will finish in a few minutes
• No added artificial colourants

On when to use it. This isn't a year-round staple — Tetra formulate it specifically for water below 10°C, when a fish's digestion has slowed down and a highly digestible food matters more than a high-energy one. Above that temperature, it isn't the food to be feeding; Tetra don't give a figure here for what to switch to instead.

Who it's for: keepers of goldfish, koi and other pond fish through the colder months, who want a specific autumn-to-spring food rather than feeding the same thing all year round.
