Sinking shrimp pellets or lobster bites should make up the majority of your crayfish’s diet. Pellet-type foods are high in protein and contain all the nutrients crayfish need to grow and develop healthy shells. Sprinkle the pellets around all of your pet’s favorite hiding spots to make it easy for it to get to them.  Crayfish can also have frozen aquarium foods occasionally, such as daphnia, bloodworms, and brine shrimp. Never feed your crayfish live or uncooked shrimp. Shrimp carry diseases that can be fatal to crays. Every now and then, cut some leaf lettuce, cabbage, zucchini, or cucumber into small strips and drop them to the bottom of the tank. Offerings like peas, carrots, and sweet potatoes are also okay. Crayfish love munching on plant matter, so don’t be surprised if they disappear in a hurry! It’s perfectly fine for crayfish to eat spoiled or decaying organic matter. In fact, treating your crayfish to veggies that are going bad is a great way to kill two birds with one stone. One or two shakes of shrimp pellets or a smattering of vegetables per day should be more than enough to keep your crayfish satisfied. Remove any uneaten portions of food soon after feeding your crayfish. Anything left sitting at the bottom of the tank will quickly decompose, dirtying the water and making more frequent changes necessary.  If you're caring for more than one crayfish (which isn’t recommended), it’s okay to double the amount of food you administer. Still, keep an eye out for leftovers and scoop them out whatever remnants you find quickly. Overeating can actually be bad for crayfish, as it causes their exoskeletons to become soft and weak.
