Layer of ice on the bottom of an ice chest covered with a garbage bag to keep the direct cold from coming in contact with the crawfish. Elevate the icechest on one end and unscrew the drain to allow the frozen ice to escape.
Close the lid. They will last for a long time this way. Replies 4. This and drain the Ice Chest often If you can tilt the chest and leave the drain plug open, this is the bast way. Oh and keep them wet.
They will last for a long time this way Did this, this weekend. Ohh well,too late to go back and edit. They don't drown, the expell the oxygen from the water and suffocate without an oxygen source. Return to Board. Jump to page. Latest LSU News ».

Being efficient creatures, they will eat their discarded exoskeleton. If you plan on keeping more than one dwarf crayfish with your betta then make sure your tank is big enough.
Luckily one dwarf crayfish and one betta can live in a 5-gallon tank together A great tank for dwarf crayfish and bettas is the Fluval Spec 5 Gallon. But at the bare minimum all you need for a crayfish enclosure is a small body of fresh water deep enough to cover the animal completely, and a rock or branch that allows it to climb out of the water without being able to escape, of course! Some time after mating the female lays about eggs, which she carries in a mass under her tail. After several weeks the eggs hatch, and a hoard of minute, perfectly formed, ravenous baby crayfish emerge.
Larger fish, such as cichlid fish and eels, will eat the young of this crayfish and sometimes the adults, too. Tetras, livebearers and dwarf cichlid fish are ideal community fish to keep with orange dwarf crayfish.
They can be kept without a heater. Crayfish can mate in autumn or in spring. However, the eggs are not fertilized and laid until the spring. Crayfish don't live very long. The males usually die after mating when they are about 2 years old. What is a blue crayfish and how rare are they?
They are a genetic oddity; a blue color morph of the common brown papershell crayfish. It is the lack of a gene that causes them to be blue. Indoor breeding of these is possible, whereas The Orconectes Immunis are not. Crawfish can live out of water for several days under proper conditions. This never seemed to harm the crayfish, but the filter will have to be replaced after they have shaved it down sufficiently.
The possibility of their digestive tract becoming impacted from the indigestible sponge material should not be completely ignored, but I have never seen any evidence of this hypothetical problem. Most likely they consume the organic matter trapped in the sponge and discard the actual sponge material itself. Temperature Crayfish come from both temperate and tropical zones, and water temperature will depend upon which species you are keeping. A heater is not required and should not be used in tanks holding most of the North American species, though species from the southern United States can tolerate temperatures as high as 82 degrees F 28 degrees C without problems.
Two very popular North American species are Procambarus alleni and Procambarus clarkii , both of which are species from the southern US.
Colorful varieties are grown in large numbers in ponds specifically for the aquarium industry. But other North American species are showing up in the trade, albeit on a much smaller scale, and in the case of these less frequently seen crayfish you should make sure you know where they come from so that you can maintain them at an appropriate temperature. As a general rule though, erring on the side of keeping North American species too cool is better than keeping them too warm, and most do well left at room temperature.
Australian species are increasingly popular, and most of those require tropical temperatures around 77 degrees F 25 degrees C. This is because at least one North American species has become widely established in British rivers, and by spreading a crayfish plague has lead to the virtual extinction of the native crayfish. Any crayfish legally sold in a British tropical fish shop will be tropical species from Australia, and consequently must be kept in a heated aquarium.
Feeding Crayfish are omnivorous scavengers, feeding primarily on plants, algae and organic detritus. Crayfish do not often find sources of animal protein such as a dead fish, and such meals are very precious to them, aggressively defending such a meal against other scavengers. But will crayfish actually kill and eat your fish? In an aquarium it is uncommon for crayfish to catch and eat healthy fish, though the odds on such an event depend on the size of aquarium, the number of fish in the aquarium, what species of crayfish is being kept, and even whether the crayfish is well fed or not.
So while it is unlikely that a crayfish will catch your fish, there is a possibility, particularly where small or slow moving fish are concerned. Most of the time crayfish are seen eating a fish that fish was already dead or dying, and the crayfish was simply doing its natural duty of being a scavenger.
Without knowing this, the aquarist might falsely accuse the crayfish of murder when he notices the crayfish chewing on the carcass! Crayfish need to be fed a small amount of food every other day or so. Any excess food should be immediately removed.
Foods to feed your crayfish include leafy green vegetables such as Romaine lettuce or other varieties ; dried seaweed like Nori; sinking pellet foods such as shrimp or algae pellets; flake food; and freeze dried or frozen foods such as fish, krill, tubifex worms, bloodworms, squid, clam, etc.
Since animal protein is rarely encountered in the wild, it is best to feed crayfish mostly plant or algae based foods, and only supplement with animal flesh. However, some aquarists feed strictly shrimp pellets with no apparent problems. If a crayfish remains soft for an extended period of time, i. Transferring the soft specimen to water with high hardness can help if this is the problem, but it is best to avoid this problem by keeping crayfish in hard water and feeding them foods rich in calcium.
Calcium can also be added to other foods by dabbing moist food with a small amount of calcium carbonate powder before feeding your cray. Crayfish sometimes die during the moulting process, a problem apparently caused by an iodine deficiency.
Iodine, in the form of potassium iodide, can be added to the water on a weekly basis to alleviate problems with the molting process.
Iodine drops sold for use in marine tanks work well for this, though a half dose rather than full dosage is all that is required. Foods that contain the algae Spirulina sp. Disease It is a very bad idea to mix together crayfish from different continents. While there is a risk of spreading disease when crayfish are placed in the same tank as another one, one disease in particular poses a very great threat.
Known as the Crayfish Plague it is carried by North American crayfish species. It is a fungus, Aphanomyces astaci , and American crayfish have apparently evolved to tolerate the fungus without much problem.
However, it is lethal to many other types of crayfish, including those from Australia and Eurasia.
