Remember that climbing out of the water is an essential requirement for the crayfish if it is not filtered. Craws need a lot of oxygen in the water. When they did not get the proper amount of oxygen in the water, they come outside of the water and breath in normal air conditions.

A crayfish can live outside water for several days due to their special gills that allow them to breathe in normal air conditions unless their gills are moist. If they live in humid weather, they can get through for months. Crayfish can reproduce all year round, with the peak period is early in the Spring. Crayfish are dioecious and have more prominent secondary sexual characteristics.

You can distinguish it from the shape of the abdomen, swimming limbs, and the claws of the crayfish. Usually, after mating, the ovary development of crayfish lasts longer. Depending on the water temperature, the ovary needs to develop for another 2 to 5 months to mature. Crayfish have a relatively small number of eggs.

According to different specifications, the amount of eggs is generally , with an average of The incubation time of eggs is about days, but under low-temperature conditions, the incubation period can be as long as months. Crayfish larvae do not need any external nutrient supply during development. Although the crayfish has fewer eggs, the survival rate of hatchlings is very high.

Of course, there are no ground dwellers who earn their living with fish poop. They should eat nutritious foods of various quality. They can be a choice for fishing when setting up a tank.

Generally, male grow faster than female, and size is also larger than the female. Like many crustaceans, the growth of crayfish is accompanied by molting.

To understand what baby crayfishes eat, we need to understand the lifecycle of a crayfish. The baby crayfishes start their life from eggs.

It takes about weeks depending on the temperature and other atmospheric conditions to hatch the eggs. The eggs hatch into larvae.

The larvae will start to look like tiny crayfishes in about 2 weeks. This is because crayfishes are known for eating their babies. The solution is simple. You just need to take the regular crayfish food and crush them to make powder. Then feed the powdered food to the babies. Suppose, you are feeding your crayfish API shrimp pellet. In case of feeding the babies, take a few pellets, crush them using something heavy and throw the powdered food in the tank.

Make sure the food particles are sinking to the bottom. So, it is important that the foods sink. Also, try to feed some vegetables once a week. You can feed them crushed baby shrimp food which is available online and in some fish stores. This usually comes in a powder form which you can sprinkle into the tank. One of the biggest problems for larvae is finding food, so providing lots of food is key to reducing mortality.

After the larval stages, young Crayfish look just like miniature adults. You can feed juveniles the same foods as adults. Just make sure you feed them every day until adulthood because they need more energy for growth.

It should be clear to see that when keeping Crayfish, their diet will be the least of your worries; they are scavengers and eat pretty much anything! Their omnivorous nature makes them easy to cater for.

They will happily eat live foods, frozen foods, fish foods and vegetables. If you care for them properly, these creatures are very rewarding to watch and are a great alternative to freshwater fish.

Hi Tim, Their average lifespan is around 2 years, some cave species live up to 10 years in the wild. Some of the Australian crayfish live for a long time. The spiny crayfish can take several years to reach maturity and then live for decades. In my aquarium I have mosquitofish, two small crayfish, shrimp and snails. My crayfish will eat my fish and shrimp when they die. Luckily they rarely ever kill my fish, but they do kill my snails, which I do like them to do because I have enough of them.

So how do I take care of them? Shrimp pellets are essential. They need this food source most. Then I feed them peas, carrots, green beans and water plants. They love a plant called anacharis? But on too of this all, and most devoured, I give them chicken and fish chunks. What should I feed them that is small enough? I put some minnows in with my blue crayfish as a treat. Now I have baby minnows. Apparently I have a very lazy crayfish.

My cray loves hotdogs, he will eat them above anything else, my grandchildren thinks its great because when given hotdogs he preforms well for their friends showing the unique way they eat I never imagined the enjoyment we would get Awesome pet. I make brine shrimp for my baby Blue Cheraxes. Lots of it. When the brine settle down and start to die in the fresh water, the baby Blues love to pick them out of the mass of Java moss, and in the sand…they even try and grab those wiggling brine swarming around when they are first put in..

This their first Ninja training. I agree with Michael about using shrimp pellets.. Also I use the baby fish food called First Bites. My big breeders love to chow down on the jave moss and Java fern the most, but also get all the other plants over growing in my other tanks, even the dead and melted leaves of them. I have a separate tank full of healthy producing Red Platys and that water is excellent for growing all kinds of plants, and yes, overpopulation of the Platys is controlled by the Cherax Destroyers!

I dip the tiny to small Platys in scalding water for before I feed them to the big blue meanies. In a couple days they disappear. I really liked the article, good coverage on getting things going!
