Why do daphnia sink deeper?
For example, large daphnia are forced to sink deeper during the day to become less noticeable for predators – after all, the deep layers of water are less illuminated. This assumption is confirmed by the fact that in water bodies in which there are no daphnia feeding fish, such migrations occur much less frequently.
How do daphnia move?
Mostly located in the water column, moving with the help of jumps, sometimes crawl along the bottom of the reservoir or the walls of the aquarium. Often they move depending on what time of day it is: when it’s light, they go deeper into the water, and at night they are at the very edge. A lot of energy is spent on these movements, therefore they must have a reason. However, it was not yet possible to find out exactly her. There are several most likely assumptions. For example, large daphnia are forced to sink deeper during the day to become less noticeable for predators – after all, the deep layers of water are less illuminated. This assumption is confirmed by the fact that in water bodies in which there are no daphnia feeding fish, such migrations occur much less frequently. There is a simpler explanation – that daphnia simply aspire to that layer of water, where the temperature and light are optimal for them, and during the day it moves up and down. From species to species, their lifespan varies greatly. Usually the pattern is simple – the largest and live longer. Small Daphnia have 20-30 days, the largest up to 130-150 days.

How to keep daphnias alive?
Daphnia seem to really thrive with a coarse air stone, especially one that’s weighted so they don’t sink. The medium sized bubbles can be at a pretty rapid ‘rolling boil’ consistency. When you position the aeration at one end of the tank, the Daphnia can swim to the other end if they want calmer water. Standard airline tubing will help keep the water flowing. Aeration is much preferred over stagnant water. This makes sense because, in the wild, Daphnia living in a pond or stream would thrive well in moving water. It really helps your yields grow.
