How do you raise crayfish?
Crayfish (or crawdads) live in aquariums.They can go extremely long periods of time without eating and they will eat gunk that is stuck to the bottom of the aquarium and live fish. Sometimes they will also eat fish food and shrimp pellets. if there are other fish living in the aquarium, make sure you cut of the crayfish's claws so they cannot catch the fish(it does not hurt them and the claws will grow back when they malt their exoskeleton). temperature and lighting do not really effect the crayfish so you don't have to worry about controling that. Every 3 to 12 months, a crayfish will malt its exoskeleton; leave the old exoskeleton in the aquarium for the crayfish to eat because this will help him grow a healthy one the next time. Crayfish like to have a rock or cave-like structure to shelter in.
