Killifish Eggs



Warning: If the temperature in your state is lower than 10C (50F), we do not recommend ordering because the eggs will be cold and damaged during shipment. If the eggs become damaged and disappear, you will receive fewer eggs than you ordered so please check the temperature before order.

We can't guarantee and responsible, that the eggs will be in perfect condition when it arrives at you. Please take a risk.

The killifish eggs are not always ready to hatch when you put them in the water. They have the expected hatching date, we identify it behind the box but uncertain. Read the manual to understand it.

Introduction of Killifish Nothobranchius

This article takes a look at the intriguing life cycle of this captivating species, shedding light on its incredible adaptability and survival strategies. Killifish Nothobranchius originates primarily in Africa, from places that have two seasons, rainy and dry. The fish die after the rainy season ends and the ponds dry up.

However, their eggs are capable of surviving in harsh conditions such as dry riverbeds, hatching when favorable environmental conditions return, such as when the rains fill up the pond, and the Nothobranchius returns to life. This adaptation allows Killifish to inhabit temporary bodies of water, such as puddles and seasonal ponds, where water availability fluctuates.

Prepare the necessary equipment

  1. Killifish Nothobranchius eggs
  2. Hatching tray and raising tray
  3. Aquarium air pump and aquarium air control valve
  4. Food
  5. Aquarium fishnet
  6. Heat lamp (optional)
  7. Dropper

Water condition

The availability of water plays a crucial role in the life cycle of Killifish

Recommended water source

  • Tap water is an easy and popular choice, as long as it has been treated to remove chlorine and adjusted the condition properly.
  • Freshwater from your aquarium
  • Bottled water. It is the most expensive way. The mineral water is not recommended because the mineral level is too high.

Recommended water condition

  • Ammonia level is less than 1.5 milligrams per liter.
  • pH between 6.2 and 8.9 (pH 7.8 is optimum.)
  • Low in salinity (fewer than 8 grams per liter)
  • Do not use any chemicals.

You can add Indian almond leaf to the water a few days before use

When added to the water, an Indian almond leaf will gradually break down and releases tannic acid, tannins, and other substances into the water.The tannic acid will lower the pH of water. If you want to reduce the pH levels in your aquarium by natural way, Indian almond leaf helps to achieve just that. The suitable temperature for Nothobranchius is between 74 and 90°F (23 and 32°C).

Food for Killifish

The killifish usually do not eat pellet food. They are opportunistic feeders, consuming a wide variety of food sources. Their diet primarily consists of small invertebrates such as insects, worms, and crustaceans.

Foods for Newly-hatched Killifish

The food should be ready before hatching the killifish eggs.

Live food in our shop

  • Fairy shrimp (Newly-hatched)
  • Rotifer

We recommence fairy shrimp. From our experience, the fairy shrimp is very easy to hatching. You should hatch 0.5/10 capsule of fairy shrimp eggs 1 day before hatching killifish eggs and use the dropper to transfer newly-hatched fairy shrimp to the killifish tray.

Other live food

  • Newly-hatched brine shrimp
  • Microworms
  • Vinegar eels
  • Infusoria
  • Grindal worms

Foods for adult Killifish

When the fry is two weeks old, it will be big enough to eat Moina macrocopa.

Live food in our shop

  • Fairy shrimp
  • Moina macrocopa
  • Daphnia magna

Other live food

  • Brine shrimp
  • Mosquito larvae
  • Tubifex worms
  • Blackworms
  • White worms
  • Fruit flies

How to hatch killifish eggs

ภาพถ่ายข้างกล่องWhen you receive it, finding ways to keep it at a steady temperature, such as in a foam box.You will see the expected hatch date behind the box. It is not precise, and the eggs may not be ready to hatch all at once.When the expected hatch date comes, open the cup and pour all peat moss into the hatching tray.

Use a small spoon to rummage peat moss to find the eggs. 

During the larval stage, the young Killifish rely on their yolk sac for nutrition. This sac provides them with the necessary energy to grow and develop.

Observe the eyes in the eggs. You can use a magnifying glass that easier to observe it. The eyes that appeared in the eggs indicate that the eggs fully developed. It would mean hatching time. Each egg takes a different time to incubate, so the hatch date is different too. However, you can hatch the eggs many times.

If you find the eye in about 10 eggs, fill the water into the hatching tray for hatching the eggs as ready to hatching. The eggs as ready to hatching will hatch within 3 hours.

If you do not see an eye in the eggs, keep them in the cup to continue incubating. Do not separate them from the peat moss. It is the most suitable medium for incubating killifish eggs.The eggs need a little moisture to incubate, so close the lid properly to prevent moisture evaporation and the egg drying out.

The newly hatched fry can not swim very well and just lying on top of the peat moss for a few hours.

These larvae are incredibly small, often measuring only a few millimeters in length. They have a transparent body, enabling them to blend in with their surroundings and avoid detection by predators.

After a few hours, transfer them very gently to the raising tray by dropper.

Hatching killifish eggs again

Some of eggs not ready to hatching in hatching tray. Two days after wetting peat moss, dry the eggs by pouring them into an aquarium fishnet and wait until all the water dripped out. You can use the paper to absorb the water under the aquarium fishnet. Then move the peat moss to the cup for incubation and start the hatching process again in 1-3 weeks.

How to raise killifish

Fill the water in a raising tray up to 0.5 inch in height at first, and feed a few foods.

Once hatched, the young Killifish undergo a series of gradual developmental changes, Gradually developing their characteristic coloration and patterns. As they continue to grow, the small fish begin to explore their surroundings, honing their swimming skills.

The growth rate of Killifish varies depending on various factors such as water temperature, and food availability.

The fry is tiny and may lose control when swimming, you should add oxygen to the water in the raising tray and set the air control valve to the lowest level. The water in the raising trays does not need to change but gradually increases the water level as the fry grows.Always keep an eye out for dead fish and remove them from the tray as soon as you spot them.Killifish are good jumpers, but the fry will not jump, so there is no need to put any cover on the tray.At three weeks of age, the fry is ready to move to the aquarium.

Normally, killifish Nothobranchius survive about a year. Killifish Nothobranchius is moderately aggressive. Sometimes males fight with each other for inbreeding with females and may bite other smaller fish. However, they have no teeth, so they can hardly do any damage.

The only male has a beautiful pattern with an adult-size length of 2 inches. The female has an adult-size length of 1.8 inches.

How to breed killifish

The only male has a beautiful pattern for displaying behavior to attract a mate. During courtship, the eggs in the female are then fertilized by the male. Then, the female Killifish lays her eggs in peat moss

ภาพไข่ใส่ถ้วยNothobranchius breeds easily. The females are prolific egg-laying machines. A fish with such a short life span will, by nature, not be fussy about sexual partners or water conditions during spawning. You can use many different types of breeding bowls. The lid prevents the peat moss from scattering in the tank when the fish are spawning. Cut a 5-cm-diameter hole in the lid. Do not cut too small a hole because the fish may injure themselves by scrapping along the edges when entering and leaving the bowl.

ภาพใส่พีทมอสในถ้วยวางไข่Peat moss is available in most fish ponds and some supermarkets. Do not confuse between peat moss and peat. The peat moss is fluffier. You can also use peat, but it will not be suitable for killifish that are peat divers.When the growth condition well, Nothobranchius become sexually mature in about two months. If you are not ready to collect their eggs, you should separate the females from the aquarium because females will lay their eggs in the gravel or on the bottom of bare tanks instead of the breeding bowl.
