If you are wondering if shrimplet are getting sufficient food after they are born, you are right to have that question because like all living things, survival is instinct.
All shrimplet are born with the instinct to survival and to be as close to food and shelter as the fundamental elements of survival. It is by no coincidence that shrimplets especially those that are relatively young within 14 days of being born.
This observation can be seen here where the shrimplet are all congregating at one particular spot in the tank. While there are some in other areas of the tank but it is very evident that most of them are near the vicinity of the kallax ball within the ceramic/terracotta dish.

In the video below, it becomes very clear that majority of shrimplet have congregate in that area. There are some found at the moss area but the most are on the feeding dish where it’s close to the food source. As shrimplets are small they thrive readily on available biofilm and kallax ball helps with that production of biofilm which the shrimplet can directly benefit.
While using the kallax ball it is important to note that it has to be soak 3 days prior to using and the effect will last up to a month, sometimes longer.
