Crayfish are small crustaceans that have similar features to lobsters, and are sometimes mistaken for lobsters and vice versa. In fact, crayfish are called a variety of different names, including crawfish, crawdads, yabbies in Australiamountain lobsters, freshwater lobsters, or mudbugs.
This can be admittedly a little confusing to someone who wants to acquire a pet crayfish, but it is very easy to distinguish between these two decapods. Crayfish are much smaller than lobsters, measuring up to six inches at the most, while the average lobster can grow to be twenty inches or more.
In the wild, they are normally found in freshwater streams or rivers, and may even be seen on land so long as they manage to keep their gills wet. Their size, unusual appearance, hardiness, and adaptable diet have made them surprisingly famous pets nowadays. Of course, the fact that they are relatively easy to care for certainly helps!

They have similar needs to fish, so if you are looking to expand your fishkeeping skills, a crayfish may just be the right exotic pet to start off with. Because their diet is so diverse, it may seem like you can just feed them anything, but crayfish will eat different foods depending on where they are bred and what stage of development they are at. Crayfish, whether in the wild or kept as a pet, are omnivorous scavengers. They typically eat whatever they can find, including any plants, fish food, or even other fish.
Always keep this in mind before you simply dump your pet crayfish in the same tank as your other pet fish, or the others could quickly become what are the entitlement programs in the us unintentional dinner!
Wild crayfish tend to eat whatever they can grab with their claws. It helps that their natural environment is composed of mud, rocks, and a fast-flowing current, as they can scavenge for food trapped in the mud and rocks or simply catch whatever flows downstream.
This current also helps to wash away any pollutants that may build up in the water. If crayfish are exposed to polluted water for too long, it may prove fatal. Their main diet consists of mostly dead fish, shrimp, or plants, as these are the food sources that are the easiest to scavenge.
The decaying flesh or vegetation is also quite easy for them to rip apart with their claws. They will even eat rotting grass, twigs, leaves, insect larvae, and amphibian eggs. If they are lucky, they may even snag a small live fish or tadpole, though this is typically difficult for them, due to the fact that they are not particularly strong swimmers and that their prey is much faster than them.
Of course, your very own pet crayfish will have a greater variety of foods to eat since you are able to choose their meal plans. It is best to vary the foods at each feeding time so that they may receive all the proper nutrients they need to thrive. Crayfish love eating decayed plant matter, so putting plants or old vegetables in their tank will help keep them fed.

This process typically takes about fifteen days, and your baby crayfish will reach about half an inch of growth. Of course, due to their size, they may be hard to see at first. Their small size also limits what they can eat. Therefore, if you know for sure that you have crayfish larvae, it is best to break down the food you give to them into much smaller pieces or find powdered food options to sprinkle into your tank.
Unfortunately, one of the biggest issues these larvae have, whether in the wild or in captivity, is the inability to find food.

The best foods to feed growing larvae and juvenile crayfish are a combination of vegetables and protein.
Protein is especially important in younger crayfish diets, as they tend to be especially aggressive feeders. When they do reach adulthood, however, crayfish become more relaxed.

Please note that if you keep multiple crayfish in one tank and do not feed them properly, they may begin to fight amongst themselves and start eating each other.

As stated before, crayfish are not strong swimmers, so they usually wait for their food to sink to the bottom of their habitat before digging in. They like to use their claws to tear up their food into smaller pieces that are easiest for them to ingest.
They will mostly use their claws and their first two pairs of legs to pick up their food and eat it. Their mouths are located underneath their antennae and are similar to the jaws of humans, only they open side to side instead of up and down. Their mandibles are actually very strong and can break the shells of other aquatic animals if need be. Crayfish also like to burrow into rocks or thin layers of sand, as it gives them both a sense of security and a shelter for when they do not want to be out and about scavenging.
Therefore, to encourage their scavenging instincts, you should sprinkle their food throughout their tank during the day so that they may discover it at night when they are more active. You can also train them to eat at certain points how to install whatsapp using cydia on iphone the day if you keep feeding them at regular intervals.

This keeps the babies safe. During this period, the babies catch floating food particles with their claws and eat those. After 2 weeks, when the babies leave the mother, they can independently live on their own. Baby crayfishes need air in their habitat. They need highly oxygenated water to live properly. The peak of the stones need to breach the water level. This way, the babies can crawl to the peak and get oxygen if there is low oxygen level in the water.
