As for the food, I completely share the view that shrimp is not a fish
and does not swallow food but is a rodent, therefore, in my opinion, it is the use of a maximum granule size of 4-6 mm for shrimp. Observing the feeding behavior of shrimps, it is noticeable that they like to carry food in their paws and gnaw it in turn.
as in the Ukrainian proverb - DON'T EAT SO I will try every particle.
