0.05 x 0.05 = 0.0025 kg feed in total per day

50% Concentrates
10% Other

Proportions (fresh product)

0.4 x 0.0025 kg = 1 g fish products
0.5 x 0.0025 kg = 1.3 g concentrates
0.1 x 0.0025 kg = 0.3 g other

Diet suggestions

Additional advice

Divide the “Feed quantity per day” over at least two feeding moments per day.
The food should be consumed within 15-30 minutes.
Depending on the fish species, supplement the diet with aquatic gel, live feed, frozen feed or small fish.
A mixture of carnivorous and herbivorous aquatic gels can be fed.
Use floating or sinking concentrates, depending on the preference of the fish species.
Make sure that the water quality parameters are maintained within pre-set ranges, as this is essential for proper welfare and health.
