3 mm pellet for goldfish and young koi, from 5 to 15 cm

Ichi Food Kido pond fish food comes as 3 mm floating pellets, in a single size, for goldfish, fantails and young koi of 5 to 15 cm. It is fed at 2 to 4 meals of 5 minutes a day, as long as the water stays between 9 and 25 °C.

These Ichi Food Kido floating pellets measure 3 mm and come in a single size only. They are intended for the small ornamental fish in your garden pond: goldfish, fantails, young koi carp and other cyprinids of 5 to 15 cm. A pellet of this size can be taken into the mouth once the fish reaches 5 cm, and it remains suitable up to about 15 cm. Beyond that, an adult swallows it without chewing and has to take many more mouthfuls, whereas the 4 to 5 mm size of the all-season floating food suits it better.

🥄 The 5-minute meal

Give the amount your fish eat in 5 minutes, 2 to 4 times a day depending on the water temperature, then remove whatever is still floating with a net. Several small meals are better than one large one, because a cyprinid has no stomach in the strict sense and digests small, repeated amounts better. The pellets stay visible on the surface throughout feeding, so you can see who comes to eat and adjust the ration from one day to the next. Feed as long as the water stays between 9 and 25 °C, measured in the water and not in the air. When it stays below 10 °C for a prolonged period, appetite drops and the floating cold-water food takes over.

🌿 Feed rations in aquaponics

What you feed ends up back in the water. The protein content determines the nitrogen load your biofilter has to handle, and here it sits at around 28%, compared with 33.5% for a maintenance feed. In aquaponics, that same ration becomes fertiliser for your plants, since the ammonium excreted by the fish is nitrified into nitrates, which the plants absorb. After a change of feed, monitor the water for 2 to 3 weeks with an ammonium test followed by a nitrite test, and the article on the nitrogen cycle explains what happens in between.

The thermometer sets the pace of feeding

It is the water temperature, not the air temperature, that decides how many meals to give and when feeding stops. A floating thermometer read in the morning gives you this value, and a precision scale or a simple graduated cup lets you weigh the first meal rather than guess it. The rest of the range can be found in the pond fish feed collection.

Resuming feeding after winter

When feeding resumes, your fish beg insistently while the biological filtration has not yet recovered its bacterial population. A normal ration given at that point supplies more ammonium than the filtration can convert, and the excess feeds the algae that turn the water green in spring. Restart with a single small meal, wait until an ammonium test reads close to zero, then increase over 2 to 3 weeks. A bag opened the previous year should be thrown away rather than used for this restart, because its oils have oxidised in the air.

This bag is only available in a 3 mm size, which is something to plan for in a pond whose population is growing. A goldfish pond renews itself through breeding, and the fish that grow end up exceeding 15 cm. You then see the biggest ones swallow several pellets at once while the small ones still catch just one: this is the sign that you need to move to the 4 to 5 mm size for the adults, keeping a bag of 3 mm for as long as young fish share the pond.

📦 The two pack sizes

The bag comes in 3.5 litres (about 1.1 kg) and 10 litres (about 3.1 kg). The first suits an ornamental pond with a few goldfish, which will finish it in a season before the feed has time to go stale. The second is for a more heavily stocked pond, where consumption justifies the volume. How long it takes to use up matters more than the price per kilogram, because pellets kept open from one season to the next turn rancid.

Frequently asked questions

6 questions

6 key questions

Is this 3 mm pellet suitable for my goldfish?

How much should you feed per day?

The rule that takes priority is the meal. Give what is eaten in 5 minutes, 2 to 4 times a day depending on the water temperature. With a floating pellet, you can check this by eye, which no percentage allows.

The percentage is for sizing a purchase. Allow 1.5 to 2% of body weight per day for adult fish in warm water. A one-year-old fish can eat up to 5% of its weight per day, a 3-year-old about 2%. For a pond holding a few kilos of fish, the 3.5 L bag covers several weeks of the good season.

From what water temperature can it be fed?

The bag states litres: how many kilos is that?

The bag is sold by volume, and the weight equivalent is shown on the packaging:

Capacity	Stated weight	For which pond
3.5 L	approx. 1.1 kg	A small garden pond, a few goldfish
10 L	approx. 3.1 kg	A full season, or a more heavily stocked pond

A floating pellet takes up a lot of space for little mass, which explains the difference from a sinking feed sold by the kilo. To size a purchase, think in kilos, since the ration is calculated on the live weight of your fish.

My fish are growing: when should I move up to the next pellet size?

Watch who comes to feed. As long as most of your fish stay under 15 cm, the 3 mm pellet is the right size.
Once the biggest ones grow beyond that size, they swallow the pellet without chewing it and take more bites at every meal.
Finish the bag you have open before starting another size, because an opened pellet goes rancid.
Then move up to the 4 to 5 mm size of the all-season floating food.
If young fish are born in spring, keep a bag of 3 mm alongside for them.
