Hikari Marine is a product line for the feeding of big and small fish by this famous japanese brand. 
qui l’articolo in italiano.
Hikari Marine sells a pellet-type fish feed in two sizes: A and S. “A” is for fish over 10 cm length while “S” is for under 10 cm fish. Unluckily the main part of mine fish is shorter than 10 cm: I tried to give it to them anyway, they’re attracted by its smell and play with it, but they can’t easily eat it.
Hikari Marine pellets have a sponge-like solidity and they’re rich of spirulina, that promotes the increment of colouration and good health for fish. Moreover, the feed turns out to be also rich of vitamin C, which is a natural anti-stress and a great barrier against diseases.
I can say that the pellets appeared to be very appetizing for the fish, but they sink in a short time. The pellets stay on the surface until the fish come to eat it, and than immediately the pellets start to sink. And they neither reach the bottom of the aquarium, but stay in the middle.
Though, it’s interesting to watch the smaller fish chasing and eating them.
On the package is correctly reported the deadline.
Composition
The feed is composed by these ingredients:
- Fish meal;
- Krill meal;
- Wheat flour;
- Yeasts;
- Seaweeds (spirulina, Arthrospina platensis, dried seaweed meal, Undaria pinnatifida, Porphyra yezoensis ueda, Porphyra tenera Kjelmann);
- Vegetables;
- Fatty and mineral oils;
- OGM soy.
The large variety that composed the feed is possible to be seen also in the macro structure of the pellets. Here below you can see a picture:
Here is an interesting nutritional analysis:
- Crude Protein 50%;
- Crude Fat 7%;
- Crude Fiber 2,5%;
- Ash 15,2%;
- Phosphorus 1%.
It doesn’t contain a large amount of phosphorus, but the fiber level is very good. Ashes are a bit high, while fats are enough limited. The “Other” slice may stay for moisture and mineral salts. For what I can understand it seems a well balanced feed, with a good protein level without their predominance.
Here below we have the additives:
- Vitamin A (Retinolo) 19.000 IU/kg.
- Vitamin D3 (colecalciferolo) 2.800 IU/kg.
- Vitamin E (alfa-tocoferolo acetato) 2000 mg/kg.
- Stabilized vitamin C (L-ascorbyl-2-polyphosphate) 490 mg/kg
- Copper (copper sulfate) 6 mg/kg.
- Manganese (manganese sulfate) 50 mg/kg
- Iodine (calcium iodate) 4 mg/kg
- Zinc (zinc sulfate) 40 mg/kg
- Ferrous (ferrous sulfate) 210 mg/kg
- Coloring
It’s necessary to notice that Vitamins are the main part, while the various sulfates are present just in small amounts.
Hikari Marine feed is given in a pocket, internally sealed by an aluminum sheet: it guarantees a easy use. The superior part has a pressure closing so the food doesn’t ruin itself after being opened. The contents is abut 110 grams.

A confection of Hikari Marine A costs 9,10 euro, and Hikari Marine S 5,60 euro. It’s about 8,3 cents per gram for the bigger sized feed and 11,2 euro for the smaller one. An information for comparing them to the 10,4 of New Life Spectrum or the 21 cents of Equo Menu Marino (review
