How to Culture Daphnia Using Green Water

Live food is essential to any ornamental fishes, especially for our guppies. Like Daphnia, It is commonly known as water fleas have a very high protein content which is good for our guppies and it is easy to culture this kind of live food.

Daphnia has two kinds, Magna and Moina. Daphnia stays in stagnant water like in the rice field and they massively reproduce by consuming these microalgae. These microalgae should be found in any green water and these are unicellular species that exist individually, or in groups.

Daphnia Culture gives an unlimited source of live food for every fish keeper. Although it has different kinds of methods, daphnias massively produce by feeding them green water. This green water has microplankton organisms which the main source of food for daphnias.

But before that, I would like to emphasize to you the food chain and benefits of daphnia for our ornamental fishes. As a fish keeper, I also use this as alternate fish food for my guppies since it has lots of benefits for my fishes.

Daphnia does not like direct sunlight, they like a cool area with a temperature of 69° F or 21° C, so make sure to put them in a shaded area or put a cover the container. Daphnia can survive for 3-4days without any intensive care.

Daphnia’s also need deep water to make them multiply while they receive direct sunlight during noon-time, most of the daphnia hides in the bottom of the container to avoid the heat in direct sunlight and suddenly crashed them.




How to Culture Daphnia Using Green Water

On this topic, I will share a few methods to culture them and massively reproduce your daphnia culture to provide your guppies an unlimited live food with a reach in high protein.

Container for Daphnia Starter

Container

Provide a clean empty container with at least 5-20 inches of height. Your container must have deep water to start your daphnia culture. Much better if the container has a wide size to rapidly multiply the daphnia.

The color of the container is not really required but if you have a dark color container it’s better. Since daphnia wants to have a little privacy during the breeding stage, It is better for them that their container is a dark color.

However, in any kind of containers like a basin, aquarium tank, or even a small container the daphnia can produce their numbers rapidly. Remember that the green water is the reason why daphnias can multiply faster.

Green Water for Daphnia

Culturing Daphnia in green water is the first step that you needed. The daphnia will consume all the small microplankton organisms that provide by the green water.

The green water came from any decomposing materials like a dead animal, fish poop, or even aquatic plants. If you want to learn more about the culturing of green water, check this content and it will help you a lot to start your green water culture.



Aerator for Daphnia

Aerator

An aerator is essential to any organisms that live in the water since it helps them to provide oxygen and reproduce massively. The Low pressure of aeration for daphnia is good enough for them to avoid that being killed. Aside from that, it also helps to circulate the green water in the container.

Yeast for Culturing Daphnia

Yeast

Yeast is one of the food sources for daphnia. Some of the fishkeepers use this material to feed their daphnia. On the other hand, it is highly recommended that do not overfeed your daphnia that might cause a sudden crashed in your culture.

Feeding them with yeast is optional since your culture starts to feed the phytoplankton in the green water. In my experience, when I try to feed them yeast it is not easy to calculate the exact amount of yeast that you need to give them, or maybe I am not lucky to this method.

Final Thoughts

The success of your guppy breeding or any ornamental fish relies on the food that you giving to them. A high content protein will be the key to the fast growth of your fishes and this is the purpose of daphnia.

Aside from the baby brine shrimp, this is the first food that we can provide to your fingerlings. It can save a lot of money if you start to culture the daphnia. Unlike the baby brine shrimp, you need to buy them in the market
