Crawfish, also called crayfish, freshwater lobsters, crawdads, yabbies, mudbugs or mountain lobsters are freshwater crustaceans that are similar to small lobsters, in which they have some relation. Just like lobsters, they have pincers and are colored brown, gray and red. They are members of the family Parastacoidea and family Astacoidea. Crawfish breathe through feather-like gills. Some of them could be found in streams and brooks where freshwater is abundant, while others live in ditches, paddy fields and swamps. Many crawfish cannot thrive on polluted water, although a few of them are hardier. Crawfish eat plants and animals, either decomposing or living and detritus. There are three families of crawfish, two in the Northern Hemisphere and the other in the Southern Hemisphere. In the Southern Hemisphere, they can be found in Australasia, South America and Madagascar. The rest can be found in Eurasia, North America and Japan. This should be enough to satisfy our curiosity about where do crayfish live so we should go next to what do crawfish eat.

How To Take Care of Crawfish
To take care of crawfish, all you need is the right kind of food and the right information about what do crawfish eat, the right tank and love and dedication. People are fond of crawfish as pets because they are so lovable to watch, when they move around the tank, eat other fish and build little mounds and hills.
- The first thing you need to do for your crawfish pet project is to set-up a 10 gallon aquarium where it is going to receive natural light and the water remains at room temperature. The best water temperature for your crawfish depends on the kind of species that you have. In general, 60 to 80 degrees Fahrenheit is a good temperature range.
- Try to copy the natural habitat of crawfish. You can do this by putting 3 inches of aquarium gravel on your aquarium. Try to arrange the gravel at the bottom of your aquarium so that it has hills and valleys. Crawfish love to hide in cracks, crevices and holes in the wild so add safe stones and logs of the right size to your set-up. A PVC pipe can also be a good substitute for logs as long as the diameter is big enough for the crawfish to crawl in. Make sure that you don’t overdo your decorations and allow the crawfish to escape from the aquarium. You may or may not add fishes to your aquarium. If you do, you can have neon tetras, platies, mollies, small catfish and swordtails for small crawfish. For bigger crawfish, you can keep smaller fish like Malawi, Tanganyika cichlid fish, catfish, South American cichlid fish, barbs, goldfish and labyrinth fish. In general, the pincers of the crawfish are too big to let them catch small fast fish.
- Place a clear lid or mesh screen top on your aquarium just to make sure your crawfish cannot get out. Lighting is not recommended because crawfish don’t like too much light in their environment.
- Add water to the aquarium until the water is at least 6 inches deep. You can arrange the tank with material that juts out of the surface in case your crawfish wants to stay on dry land.
- Set up a filter. A hanging filter that has a stream of water going into the tank with the uptake immersed will give a water flow that benefits the crawfish. Run the filter for 24 hours before you proceed.
- Place your crawfish in a bag or container in the aquarium for 1 hour so that the water levels will acclimate. Then, release your crawfish.
- Feed your crawfish once a day.
- Clean the aquarium regularly and perform partial changes of water once every week.
