Crayfish
Crayfish (also called crawfish or crawdads) are freshwater crustaceans that look like a small lobster. Crayfish feed on plants, frog eggs, insects, and small fish. Crawfish boils and dishes with crayfish in them are very common in Louisiana. Louisiana supplies about 95% of the crayfish harvested in the US.

Crayfish exchange gases through gills located underneath their carapace. Water is drawn in through the crayfish's openings and passes over the gills, where oxygen is absorbed and carbon dioxide is released.
Native species of crayfish that are are a normal part of the ecosystem are not harmful. But there are several invasive species, like the rusty crayfish, that can kill off native crayfish and other crustacians. The rusty crayfish has a thicker shell and less "meat" and therefore are are not a good part of the food chain depriving the ecosystem of the nutrients from the crustacians it replaces. Invasive species also tend to destroy large amounts of water plants that further degrade the food chain. Also there is an infection that occasionally occurs in crayfish that can spread to other animals but this is usually a normal part of the life cycle and not neccasarily harmful.
Does crayfish live in freshwater?
Most crayfish can tolerate a small amount of salt, but there are none that I know of that can tolerate full strength seawater. Most can tolerate brackish water for short periods of time, but extended exposure will kill them. They are adapted to freshwater environments, and freshwater is best for them.
It would be very difficult for a grizzly bear to eat a lobster. Most grizzly bears fish in rivers and creeks. I suppose a grizzly could wander near an ocean, but it would be very difficult for them to find a lobster that is a bottom-dweller. They also would be unsure how to open the lobster to get to the meat.
they will eat algae pellets (easily found in most pet stores. and dead fish and clams (freshwater)all i found was tropical fish food and small fish.
they don't there not very social they usually kill each other for food and most stuff so there communication is really in fighting "i once caught a crayfish and it's claws were an inch long i can send you a picture give me your email at jjjmaui@gmail.com"
Yes, much like other living species, fiddler crabs do sleep. However, they tend to only sleep when its between 75-85 degrees, as this is when they are most comfortable.
Would crayfish do well with koi?
Sometimes fiddler crabs or other crab species are sold for aquariums. Most require brackish or even saltwater. Few thrive in freshwater. Most require live insects, worms, and/or small fish to eat. They can harass or kill other small animals in the tank with them. Many have nasty pinchers. For this reason, they are best suited to a set-up solely for them. Almost all of the crabs sold for "freshwater" tanks require a haul-out spot. The water level must be low enough to allow them to get in and out of the water with ease. If denied the ability to get out of the water, they will eventually die. They most likely also require full spectrum lighting over the basking site but studies probably have not been done on this. Fiddler crabs and similar species stay relatively small, at a few inches in size.
Why do crayfish need to still be alive?
the cray fish send to the factory alive because when they send it they put it into ice and when we want to eat it will be so fresh!
