Baby Crayfish – 20 Facts And Careguide!

If you are a fan of crayfish, then you will be excited to learn about baby crayfish. These little creatures are fascinating and can be found in many bodies of fresh water, but not in seawater, as crayfish are strictly freshwater animals.

In this blog post, we will discuss everything you need to know about baby crayfish – from how they are born, to what they eat, to how long they live. We will also provide some tips on how to care for them if you decide to raise your own!

How are baby crayfish born?

Baby crayfish are born from crayfish spawn. Spawn is simply the term used for the eggs that are released by female crayfish.

Spawning usually occurs in the late winter or early spring, when the water temperature begins to warm up.

Once the eggs are released, they will sink to the bottom of the water and begin to hatch. It typically takes a few weeks for the eggs to hatch, and once they do, the baby crayfish will emerge.

How many babies can a crayfish have?

A female crayfish can lay anywhere from 100 to 200 eggs at a time. However, not all of the eggs will hatch – typically only about 50% of them will survive.

How long does it take for crayfish to have babies?

It takes about two to three months for crayfish to have babies. This is because it takes a while for the eggs to hatch and for the baby crayfish to grow big enough to mate.

How long does it take for marbled crayfish eggs to hatch?

It takes about two to three weeks for marbled crayfish, and most other crayfish, eggs to hatch. The eggs are carried by the female until they hatch, however, the mother does not need to stay near the eggs once the baby shellfish have been released.

When is the crayfish spawning season?

The crayfish spawning season typically begins in late winter or early spring, when the water temperature begins to warm up. This usually happens a few weeks before the ice on the water melts.

What do baby crayfish eat?

They will eat mostly microorganisms, such as algae and plankton. As they grow, they will gradually begin to eat larger prey items.

Baby crayfish are tiny, and so they require a diet of plant or animal matter that is small and easy to digest. 

When they grow larger they will eat decomposing matter (dead fish and plant material) and aquatic vegetation as well as snails, tadpoles, and other tiny animals that live in their habitat.

In general, adult crayfish will eat most foods that are available to them in their freshwater habitat and are not picky.

How to feed pet newborn crayfish?

If you have pet baby crayfish, it is important to make sure that they are getting the right kind of food. You can buy special food pellets for crayfish, or you can also feed them small pieces of raw shrimp, fish, or liver. You can also feed them mixes such as reef roids.

They will also feed on leftover food material from the other animals in your aquarium and dead plant matter when it falls to the ground. Baby crayfish cannot catch larger prey items on their own, so it is important to make sure that they are getting the right size food.

What do baby crayfish eat in the wild?

In the wild, baby crayfish will eat mostly microorganisms, such as algae and zooplankton. As they grow, they will gradually begin to eat larger prey items. Just like crabs, they play an important role as decomposers in the ecosystem, and so they will also feed on dead plant- and animal matter when it falls to the ground.

Where do baby crayfish live?

Baby crayfish live in the same places as adult crayfish. They can be found in many bodies of water, including lakes, rivers, and streams.

Small crayfish often hide among plants and rocks to stay safe from predators!

As they are small and vulnerable, they will tend to stay underneath objects such as rocks and mostly move around in the shadow, making it harder for predatory fish to spot them!

What do baby crayfish look like?

Baby crayfish are very small – about the size of a mosquito and without much color compared to the adult crayfish.

They are transparent with pale brown or red color patches, and they have a soft shell that is easy to damage:

How old do crayfish get?

Crayfish can live at least three years! Due to their hard exoskeleton and ability to regenerate limbs, it is hard to be sure how long they live. Some people have reported that one of their crayfish lived for more than 10 years, but they can’t really know for sure.

How do you care for baby crayfish?

If you decide to care for baby crayfish, there are a few things you need to keep in mind. First, you will need to provide them with a tank that is large enough for them to grow in.

Crayfish are great scavengers, and one of the best ways to introduce them into your environment is with a used tank – this will ensure that they’ll already have shelter and something which they can use for food in the form of decomposing plant matter.

But be carefull not to keep crayfish, especially baby crayfish, with fish that will eat them!

Cleaning your tank regularly will help to keep the water quality up, and this will reduce stress levels for the crayfish. You should also make sure that you choose a species that is suitable for the size of the tank that you have – tropical species won’t be able to survive in cold water, so something like a dwarf crayfish would be much better suited to a beginner.

Additionally, you should make sure that the pH level is suitable – those originating from America tend to do much better in acidic water (ideally at pH 5 or below), whereas those from Africa and Asia need alkaline conditions (pH 7 or above). It’s also important to ensure that the aquarium has a lid, as these creatures are great climbers and will be trying to escape through the water surface.

Crayfish are known for their appetite for small fish and can eat the dead fish in other aquariums. You can also use live meals and shrimp pellets as a source of protein for your crayfish.

The key to keeping them healthy is to maintain a balance between their diet and their growth stage (age). You should also consider providing your crayfish with vitamin supplements to boost their immune system and prevent molting problems.

Crayfish need to molt in order to grow, and this process can take several minutes or even hours depending on how big they are. They become incredibly vulnerable during this time, so you should try to minimize disturbances to your tank.

Just after hatching, you might want to remove or feed the mother crayfish as crayfish are known to eat their own babies!

You should also not start to introduce any larger fish into the aquarium when the crayfish are small. It’s also important to make sure that you remove dead crayfish immediately, as these can quickly pollute an aquarium if left for too long.

The water should be clean and oxygenated, and you will need to feed them a diet of microorganisms, algae, and zooplankton along the way.

Finally, It is very important to keep an eye on the tank temperature and pH to make sure it is consistent, as baby crayfish are very sensitive to changes in their environment!


Baby crayfish are born looking like adults but way smaller! Most types of crayfish give birth to 20-30 live young at a time, which is already able to swim and crawl around.

Baby crayfish begin life eating smaller particles like their parents, but eventually mature enough to move out and survive on their own.

Although they are sensitive to water conditions, baby crayfish quickly grow into more sturdy creatures able to fend for themselves and even regenerate their limbs if lost!
