Daphnia prefer 64-72 degrees Fahrenheit.
Daphnia live in lakes, ponds, slow moving streams.
Yes, Daphnia cannot regulate their body temperature
No, Daphnia cannot live in an aquarium with fish as they are likely to be eaten by the fish.
Daphnia are cold-blooded animals, meaning their body temperature is not regulated internally but instead fluctuates with the temperature of their environment.

To investigate the effects of temperature on Daphnia, you can set up multiple tanks with Daphnia under different temperature conditions (e.g., room temperature, heated, and cooled). Monitor their heart rates or movement over time using a microscope with a camera. Record and compare the responses of Daphnia at different temperature levels to observe any changes in their behavior or physiology.
As temperature increases, the heart rate of Daphnia generally increases as well. This is because higher temperatures can lead to an increase in metabolic rate and enzyme activity, causing the heart to beat faster to circulate oxygen and nutrients throughout the body. However, there is an upper limit to this relationship, as extremely high temperatures can eventually become detrimental and even fatal to Daphnia.
Yes. Aslong as the gold fish (coldwater fish) and the pleco (warm water fish) do not go into one extreme or the other on the temperature scale. Your plecostomus will look like it is eating your goldfish if it doesn't get enough food.
Daphnia, commonly known as water fleas, typically have a lifespan ranging from a few weeks to several months, depending on environmental conditions and species. Under optimal conditions, some can live up to around 2 to 3 months. However, factors like temperature, food availability, and predation can significantly influence their longevity.
No, Daphnia can not eat Hydra, Because the Hydra has tentacles to capture the Daphnia and eat it. The Daphnia therefore can not get free which means the Hydra can eat the Daphnia. The Hydra therefore has more force and can eat the Daphnia. Your answer is NO.
Daphnia, commonly known as water fleas, are small crustaceans that are found in freshwater habitats such as lakes, ponds, and streams. They are typically planktonic, meaning they float or drift in the water column. They can be found worldwide in both tropical and temperate regions.
