Crawdads are small, lobster-like crustaceans that can be found in most freshwater sources around the united states. They are opportunistic scavengers, territorial, mildly aggressive, and the favorite snack of painted turtles. Most people use them as bait, or as food for their pet turtles. Some fish owners us them to help keep their tanks clean, but I will be telling you how to keep them as pets. They can be very interesting and entertaining animals for those who take the time to appreciate them.
Catching
You can find crawdads in most pet stores, but if you're like me and enjoy catching your pets, this should help you out. Crawdads can be found in most rivers and lakes near the shore. They like to hide under rocks and logs until nightfall when they venture out to hunt, but they will greedily eat anything that comes close enough for them to grab. There are several methods for catching these animals, but my favorite is probably the easiest. Just take a fishing pole with a piece of worm on the end of it, or even a simple piece of string with meat tied to one end of it. Lower it into the water in front of several rocks and wriggle it a bit.
If there is a crawdad present, it will come out and grab hold of the bait. Most crawdads are too greedy to let go of a meal. you can usually pull them right out of the water and lower them into a bucket. If this is too boring for you and you like to get you feet wet, you can also go around turning over rocks with a butterfly net or mino net in hand to scoop the little guys up. Keep in mind that crawdads can swim backwards very fast using their tails. You can also lure them out of their hiding spots with bait and then use a net to catch them; this is a much less destructive method.
Housing
Any aquarium bigger than 5 gallons should be fine for a single crawdad. Make sure the water is at least 3 or 4 inches deep, (deeper water won't bother him) and provide hiding places for your new pet; crawdads are very shy creatures and may become stressed if there is no shelter. You also need a good lid with no large holes. Crawdads are surprising climbers and can even jump out of the water like a dolphin when they want to, so you have to escape-proof your setup. One of the biggest problems in keeping crawdads is the PH level of your tank, it needs to be neutral, or 7. An easy way to regulate this is with eggshells. Just take a few bits of eggshell from your breakfast, sterilize it by boiling or microwaving, and put it in the tank.
If the tank gets acidic it will dissolve the eggshell and balance the tank again. Your crawdad will also eat the shells to replenish its own minerals and stay healthy. For substrate, gravel seems to work well, and it helps to have at least one tank decoration that sticks out of the water. Crawdads love to climb at night and can venture out of the water for short periods of time. You also need to keep the temp between 70 and 80 degrees for a healthy pet. Crawdads breath with gills, so you will need to aerate the water just like with a fish. Crawdads will eat aquatic plants so keep this in mind when making your setup. I also recommend getting a piece of driftwood or a rock from a river as it will have bacteria necessary for a well balanced tank.
Feeding
Crawdads will eat nearly anything they can get hold of, but they don't actually need that much food. If you are keeping a crawdad by itself, a small amount of sinking fish food twice a day should be plenty. You don't need to place the food near your pets hiding spot as it will smell the food and go out looking for it. If you are keeping it in a tank with fish, then it will eat the leftovers from when you feed them.
Friends
Crawdads are very solitary animals and don't like others of their own kind in close proximity. If you are going to keep more than one of these territorial little guys, make sure you have a large tank, hiding spots on opposite ends, and food dropped in different places so they don't fight each other. Even with these precautions there is the possibility that they will fight and injure or even kill each other. As for other animals such as fish, crawdads will kill anything they can catch and overpower, but if your fish are large and healthy they should be able to stay away from crawdads on the bottom. Algae eaters, despite being slow bottom feeders, seem to get along well with crawdads for some reason, so you shouldn't have to worry about that, but any fish that is sick or weak will probably be eaten by the crustaceans. What ever you do, do NOT put you crawdad in with turtles unless you want him to be a snack. Painted turtles love to eat crawdads.
