Interesting animals, crayfish are a great way to liven up an aquarium. However, if you’ve never kept one before, you may be curious about what these creatures actually eat. Knowing what to feed them is essential for both their wellbeing and the upkeep of a healthy aquarium environment. The varied diet of crayfish, sometimes referred to as crawfish or freshwater lobsters, can occasionally surprise new aquarium owners.
In their native environment, crayfish are scavengers. They eat a variety of detritus, small aquatic animals, and plant matter. It follows that they can survive on a varied diet that closely resembles their native food sources. You can feed them veggies, occasionally protein sources, and crayfish food that has been specially formulated in an aquarium. They enjoy nibbling on blanched spinach, zucchini, and even tiny shrimp or fish pieces.
Remembering that crayfish can be quite active foragers is important. They frequently sift through substrate in search of edible morsels because they enjoy scavenging for food. In addition to keeping them healthy, giving them a varied diet satisfies their innate foraging instincts. You can make sure your crayfish are well-fed and happy in their aquatic habitat by providing a variety of foods and paying attention to their preferences.

Features of crayfish nutrition
Gender. Gender influences the amount of food and diet that river crustaceans consume. Males eat once a day, every day. Additionally, females only eat once every three days, but they eat far larger portions.
Time for feeding. Crustaceans in rivers are nocturnal. As a result, those who own these kinds of pets at home should feed their pets in the evening.
Portion size. It’s easy to figure out how much food is needed. Overeating is not common among river crustaceans. Therefore, just setting up a feeder in the aquarium and adding food to it will suffice. A fresh portion of food should be added to the container as soon as it is empty.
It is not advised to use excessive amounts, though. Food residues add to the aquarium’s pollution, so cleaning is necessary at least once every two days to prevent the growth of putrefactive processes that endanger the health of aquarium occupants.
What river crustaceans eat in natural conditions
Crustaceans eat mostly plants; only 10% of their diet consists of animal products.
In their native environment, crayfish feed on:
- phytoplankton;
- algae;
- organic matter;
- small invertebrates.
Time of year. However, the season and several other variables affect their taste preferences. For instance, crayfish prefer protein food in the form of worms, tadpoles, larvae, mollusks, and small fish during the breeding season or winter.
Crayfish do not eat carrion, despite what the general public believes. Alternatively put, they may consume it, but only in dire circumstances, meaning when all other food sources are exhausted.
Crayfish can live in the water as well as on land, and their diet grows significantly during the warm season.
Crustaceans enjoy eating a wide variety of plants’ stems, leaf blades, and roots.
Features of feeding river crustaceans at home
The food that river crustaceans eat in their natural habitat varies greatly from that of their artificial habitat. Aquarists must understand what to feed their pets and how to do it to keep them safe from several illnesses and early demise.
Since river crustaceans are omnivores, food selection is typically not an issue. You can add the following to your pet’s diet:
- bread crumbs;
- chopped pieces of meat of any kind;
- cereals;
- various cereals;
- pieces of fresh vegetables and fruits;
- greens;
- nettles;
- earthworms.
You can also buy specialty food made just for crustaceans, which is available at any pet store.
For example, ornamental fish are fed river crustaceans, which prefer the following kinds of frozen or live food:
- small mollusks;
- cyclops;
- daphnia;
- rotifers.
Crustaceans need protein foods as well, but their diet should still be primarily plant-based.
The most crucial thing to remember is to keep an eye on the serving sizes of the food.
Feeding food should not exceed 3% of the crayfish’s body weight, according to experts.
If not, arthropods will perish from the rot and decomposition of the leftover food.
Crayfish are amazing animals with a wide range of food options that can significantly affect both their well-being and the harmony of your aquarium. Being opportunistic omnivores, they consume a variety of foods, including small animals, plants, and even trash. You can feed them specific crayfish pellets in an aquarium, blanched veggies, and occasionally treats high in protein, like shrimp or fish. Knowing what crayfish eat will help you keep your tank clean and balanced while also ensuring their success.
Natural food for crayfish
It is possible to facilitate the feeding process by preparing an artificial reservoir ahead of time specifically designed to house crayfish. It only takes a few plants to achieve this on the aquarium’s bottom:
By providing the ideal level of nitrogen to the soil and aquatic environment, these plants have a positive impact on both. Most significantly, they can be eaten by crayfish.

Pellets | Specially formulated crayfish pellets are a convenient option that covers their dietary needs. |
Fruits | Some fruits, like apples and oranges, can be given in small amounts as a treat. |
Decomposing Material | Crayfish naturally scavenge and will eat decomposing leaves or plant matter in their habitat. |
It’s essential to know what crayfish eat in order to maintain their wellbeing and growth in your aquarium. The varied diet of these amazing animals is a reflection of their opportunistic nature. They scavenge for a range of foods in the wild, such as dead fish, insects, and plant matter. In captivity, this natural behavior can be replicated by providing a well-balanced diet that includes both commercial pellets and wholesome, fresh foods.
Commercial crayfish meals are designed with care to fulfill their nutritional requirements, offering vital vitamins and nutrients. On the other hand, adding fresh foods to their diet can improve their health and coloring. Vegetables like spinach and peas are popular foods for crayfish, and they also occasionally eat shrimp or tiny pieces of fish as a source of protein. With this variety, you can be sure they’re getting a balanced diet that promotes healthy growth and general wellbeing.
It’s also crucial to keep in mind that crayfish are notoriously messy eaters. Food particles can be dispersed throughout the tank, so routine cleaning is required to avoid problems with the water’s quality. Your crayfish will live a happy and healthy life if you feed them a varied diet and keep the tank clean. Take pleasure in watching these fascinating animals in your aquarium as they investigate their food and display their natural behaviors!
