Crayfish, which are also known as freshwater lobsters, are interesting and unique pets that can make any aquarium more colourful and interesting. They are quickly becoming a favourite among aquarium hobbyists because they are curious, have bold claws, and are very active. You need more than just clean water to take care of these crustaceans. It starts with the right food for pet crayfish.
Knowing what your crayfish eats is essential for its health, growth, and the way it sheds its skin. A healthy diet will give you a strong shell, bright colours, and a longer life. This guide will cover everything you need to know about feeding your crayfish, including what they eat in the wild, the best foods to give them, when to feed them, and expert tips on how to care for them so they stay healthy.
How Crayfish Eat in the Wild
Crayfish are scavengers in the wild. They look for food in rivers and ponds, where they consume a wide range of natural materials. Because they eat both plants and animals, they are omnivorous.
Crayfish naturally eat:
- Plants and leaves that are rotting
- Little fish or bugs
- Worms and snails
- Algae and biofilm are growing on rocks.
This wide range of foods gives them the protein, fibre, and minerals they need to live. To do this in your aquarium, you need to give your crayfish a mix of plant-based and protein-rich foods to keep them healthy and happy.
Why do pet crayfish need to eat a balanced diet?
It’s not enough to keep your crayfish full; you also need to make sure they stay healthy for a long time. A balanced diet helps your shell grow, your colour get better, and your immune system get stronger.
If crayfish don’t get the proper nutrients, they might:
- Make weak shells and break when they moult.
- Lose their bright colours.
- Get lazy or angry
- Have trouble growing
Giving your pet crayfish a variety of foods makes sure they get proteins to help their muscles grow, calcium to make their shells stronger, and plant matter to help them digest.

Sinking Shrimp Pellets
Sinking Shrimp Pellets are the one of the easiest foods for crayfish to eat is sinking pellets. These pellets are easy for crayfish to reach because they live and eat at the bottom of the tank.
Shrimp pellets that are high in protein, calcium, and amino acids are what you want. These nutrients are essential for healthy moulting and keeping the shell colour bright.
Some brands that are recommended are:
- Hikari Shrimp Cuisine is high in marine proteins and algae.
- Omega One Shrimp Pellets are made with natural ingredients and no artificial colours.
To keep the water clean, give them small amounts of food once a day and take away any food they don’t eat.
Wafers of algae
Algae wafers are a great way to get fibre and nutrients from plants. They look like the algae that crayfish would eat in the wild, and help with digestion.
Give them algae wafers 2–3 times a week in addition to their main protein diet. These wafers also help them get the right amount of nutrients by giving them minerals and antioxidants.
Tablets for Bottom Feeders
Bottom feeder tablets are a great all-in-one choice for aquariums with a mix of species, like crayfish and other fish. These tablets have a blend of proteins, vegetables, and vitamins that sink quickly and are easy for bottom-dwelling animals to eat.
Pick formulas that don’t have fake fillers like soy or wheat, because these don’t add much nutrition to crayfish.
Pellets made just for crustaceans
Look for pellets made just for crustaceans if you want to give your crayfish the best food possible. These have extra calcium, magnesium, and trace minerals that help the shell harden after it has moulted.
You can keep your crayfish’s shell strong and colourful by giving them these special pellets two to three times a week.
Pet Crayfish Food That Is Natural and Made at Home
Giving your crayfish natural or homemade foods along with store-bought pellets is a great way to mix up their diet and keep feeding time fun.
New Vegetables
Crayfish love fresh vegetables because they are full of vitamins, minerals, and fibre that help them digest food and make their shells stronger. Before you feed them to your dog, lightly blanch the vegetables to make them softer.
The best vegetables to choose are:
- Slices of courgette
- Leaves of spinach and kale
- Peas (without the shells)
- Carrots
- Cucumber
Please give them a small piece every day or every other day. To keep the water clear, take out the leftovers after 24 hours.
Foods high in protein
Crayfish need protein to help their muscles grow and their shells grow back. You can give them small amounts of animal protein a few times a week.
Some examples are:
- Shrimp or fish that has been cooked without seasoning
- Pieces of boiled egg white
- Bloodworms that are frozen or alive
- Shrimp in brine
Feed them in moderation because too much protein can make the water dirty and make them aggressive towards other fish.
Algae and leaf litter that are already there
Crayfish in the wild often eat algae and leaves that are breaking down. You can do this by putting Indian almond leaves or oak leaves in your tank. They give off tannins and nutrients over time and are a natural food source.
Crayfish also eat algae that grows naturally on rocks and tank walls. This is a healthy snack that doesn’t need much care.
How often to feed and how much to feed
It’s just as important to feed your crayfish the right amount as it is to feed them the right food. If you feed your crayfish too much, the water can get dirty quickly. If you don’t feed them enough, they might attack other fish in the tank.
General rules for feeding:
- Once a day, give adult crayfish food.
- Give them only what they can finish in five to ten minutes.
- Juvenile crayfish do better with two smaller meals a day.
- Keep an eye on how much your crayfish eats and change the portions as needed. It’s normal for your crayfish to eat less when they are moulting.
Things You Shouldn’t Feed Crayfish
Crayfish can’t eat all kinds of food. Some can hurt their digestive system or make the tank dirty.
Don’t feed:
- Salty or oily foods are bad for people’s internal organs.
- Raw meat or poultry could cause infections from bacteria.
- Citrus fruits are too acidic for their exoskeleton.
- Bread or pasta: bad for your health and makes too much waste.
- Always put fresh, natural, and safe fish foods first.
How to Feed Your Kids in a Healthy Way
Your crayfish will stay healthy and happy if you stick to a regular feeding schedule.
Feed at night: Crayfish eat better in the dark because they are nocturnal.
Clean up leftovers: Take out food that hasn’t been eaten to keep the water clean.
Give them places to hide: Crayfish feel safer eating when they have a place to hide.
Change up their food: Give them vegetables, pellets, and protein in that order.
Add calcium sources: Crayfish need calcium to shed their skin. Put crushed coral or cuttlebone in the tank.
If you feed and clean your tank regularly, your crayfish will stay healthy and active.
Why it’s essential to have a good feeding schedule for your pet crayfish
Properly feeding your crayfish does more than keep them alive; it also makes them live longer, look better, and act more naturally. A balanced diet helps with frequent, successful moulting, makes the shell colour better, and encourages active scavenging.
Crayfish owners say that their pets are more lively, colourful, and interactive when they feed them a mix of pellet food, fresh vegetables, and protein sources from time to time. Good food for your crayfish doesn’t just help them; it also helps the whole ecosystem in your aquarium.
