Crayfish do best when given the run of a spacious tank. However, they’ll generally live in relative harmony with small fish like goldfish, barbs, mollies, swordtails, and neon tetras. Crayfish may display some aggressive tendencies from time to time, but they’re usually too slow to catch and eat the much-faster fish.   Crayfish typically only attack sickly fish that sink toward the bottom of the tank. If you discover your crayfish devouring one of its tankmates, chances are it was close to death anyway. There is a more aggressive option if you plan to keep crayfish in a community tank, to cut half of the inner claw to prevent any nipping or aggressive action with a sterilized knife or scissor. This still allows the crayfish to pick up food. Every few months, carefully cut the tips of their claws to ensure they don't start nipping fins again. While crayfish don’t pose much of a threat to other fish, the reverse isn’t always true. Large species like cichlids and catfish have been known to attack crays, often resulting in the injury or death of one or both creatures. It's not recommended that you keep more than one crayfish in a tank. If you do, it will be important to make sure they have plenty of space to themselves, and that they’re the same species. Crayfish of different species are more likely to try to kill each other. Every few months, your crayfish will shed its outer shell to make room for a new one large enough to accommodate its growing body. You may be tempted to remove the old shell afterwards, but don’t. It will feed on the shell for several days in order to extract the nutrients and minerals it needs to create a strong new layer of armor.  Don’t bother feeding your crayfish in the first 3-5 days after it molds. During this time, it will only eat the old exoskeleton.  Add a few drops of potassium iodine to the tank when your crayfish begins exiting its shell. Molting crayfish have been known to die off as a result of iodine deficiency. You can find potassium iodine at any store that stocks aquatic...
