Its composition is similar to the Vitalis Marine Pellet, which we talked about last year. The vitamins are the same, while the analytical composition is slightly different.
But the main feature of Vitalis Marine Grazer Mini is its unusual shape: a thick disk with a hole in the middle. This shape is incredibly useful; you can even insert the food in a special suction cup and then hang it inside the aquarium. The fish come and graze on it as they would do with food in the wild. They peck the food a little, go away, and come back. Spectacular.
Just remember to take the uneaten out after a few hours in order to prevent it from decomposing. The fish really like it! Moreover, it’s very soft so you can pull little tidbits off of it, which the bigger fish like very much.
Like its “brothers” Marine Grazer Mini is made from the usual fish flour, with molluscs, crustaceans and vegetable products. It’s a complete meal for fish that eat more than algae.
Marine Grazer Mini is available in two sizes, one for public aquariums (and it loses the suffix “Mini”), and one for us aquarists.
Composition of Vitalis Marine Grazer Mini
The feed is made with the following ingredients:
- Fish flour and derivative products;
- Vegetal derivatives;
- Molluscs and crustaceans ;
- Oils and fats;
The nutritional analysis, which shows a predominance of proteins:
- Raw protein 31.9 %;
- Raw oils and fats 12 %;
- Raw fiber 4.5%;
- Inorganic matter 18.6 %
- Moisture 21.3%
- Other 11.7%
Pictured below is a visual representation of the same analysis:
As we can see from the chart, the food is mainly protein, though in smaller quantity than the Marine Pellets from Vitalis, and has 12% fat. Because of this, it’s suitable for fish that normally eat other fish or crustaceans. The protein count is far below the quantity of similar food (50.3%), while the fats are slightly over (10.5%). The fibers, on the other hand, are more than the double: 4.5% compared to 1.9%. The remainder is moisture and inorganic matter, which is often assimilated to the raw ashes in other feeds.
The analytical composition stops at 88.3%, so we don’t know about the remaining 12%. Moisture, other, and inorganic matter is over 50%.
Now let’s see the analytic composition of vitamins, trace elements, and additives:
- vitamin A 15,000 IU/kg.;
- vitamin D3 2,000 IU/kg.;
- vitamin E 200 mg/kg.;
- Astaxantina 133 mg/kg.;
- Zinc (sulphate monohydrate) 208 mg/kg.;
- Iron (sulphate monohydrate) 28.7 mg/kg.;
- Manganese (manganic sulphate monohydrate) 131 mg/kg.;
- Copper (pentahydrate copper sulfate) 88.5 mg/kg.;
- Iodine (anhydrous calcium iodate) 12.4 mg/kg..
In the first one, comparing the vitamins, we can see that Vitamin A is predominant. Remember that vitamin A promotes healthy growth, strengthens eyesight, protects the skin, and acts positively on fertility.
Vitalis Marine Grazer Mini comes in only one size, 110 grams, and costs 13 euro (about 11.8 cents per gram).
In comparison, Hikari Marine A has a cost of 8.3 cents per gram, while the smaller Hikari Marine S is 11.2 cents per gram. Then there is 10.4 for New Life Spectrum, 11.3 for XAqua Marine, 21 for Equo Menu Marino, 29.5 for Elos SVM2, 15.6 cents per gram for Unica Gran Premium Plus, 12.3 for AquaForest Marine Mix S and 14.2 for Marine Pellets by Vitalis.
