- Feeding purpose: choose the everyday, growth or cooler-water recipe that suits your pond.
- Pellet and pack: select the size your fish can take and an amount you can use while fresh.

Probiotic and prebiotic do not mean the same thing
Check how the manufacturer describes the ingredient in the selected recipe. Do not treat a prebiotic ingredient as evidence that the food contains live probiotic organisms. Likewise, garlic, propolis or a health label does not establish that a food prevents or cures a particular fish disease.
Choosing Health & Probiotic Koi Food
A probiotic contains live microorganisms; a prebiotic is an ingredient used to support beneficial microorganisms. The terms are not interchangeable, and a food containing garlic, propolis or yeast-derived ingredients should not automatically be called a live probiotic. Diet is part of routine care, alongside suitable water quality and feeding quantities.

Published declarations are linked above. Guaranteed minimums, typical figures and exact declarations are labelled as such where stated; they are not our laboratory measurements. A dash is not zero: we have not used an unverified number or calculated a blend’s analysis. Pellet options refer to the shop listings; check the selected format and supplied pack. Recipes and pack labels can change.
Open each food for its full feeding instructions, available options and current stock. Compare the exact recipe and pellet format rather than the brand name alone.
Keeping food in the context of everyday care
A suitable diet is one part of keeping koi in good condition. Watch their appetite and behaviour, check water quality and keep the pond’s routine care up to date.
If a fish is unwell, investigate the cause separately. A probiotic, garlic or propolis ingredient does not make the food a treatment for disease. Introduce food changes gradually and keep portions matched to what the fish are eating.
Pack size and freshness
Choose a quantity that can be used while fresh. A larger pack is useful only if it suits the feeding rate and can be stored correctly. Litres measure volume and kilograms measure weight; compare declared food weights where possible. Keep food sealed, cool and dry, use a dry scoop and follow the pack’s best-before date.
Common questions
What is the difference between probiotic and prebiotic food?
A probiotic formulation includes live microorganisms. Prebiotic ingredients support beneficial microorganisms. A product containing yeast extracts, glucans or garlic should not automatically be described as containing live probiotic bacteria.
Is health food a treatment for disease?
Food supports nutrition and condition. Investigate water quality or fish-health problems separately and follow appropriate treatment guidance when needed; the food’s name does not make it a medicine.
Do probiotic growth and wheatgerm foods have the same recipe?
No. NT Labs Probiotic Growth, Multi-Season and Probiotic Wheatgerm have distinct analyses and feeding guidance. Compare the named formula and pellet option.
Compare current pack prices and price per kilogram
Prices follow the current product prices and sale prices, using the net food weight. They use the same tax display as the shop and exclude delivery. Compare the same recipe and pellet size; a larger bag is only better value if you can use it while fresh.
