Yes, fish can eat dog food. But should you use dog food for feeding fish? The answer to that question is no, and you should not. Plenty of fish can die because of eating dog food regularly.
Logically, dog food is created while keeping dogs in mind. The concentration of nutrients and vitamins in dog food is added according to the dog’s weight and size. As there is a massive difference in the size of a dog and fish, you cannot feed them to a fish.
Why Can’t Fish Eat Dog Food?
As a pet fish owner, you would want your pets to achieve proper nutrition so that they can grow properly. But if you feed your fish dog food in their meals, then they will not be able to grow to their full potential.

How Is Dog Food Different From Fish Food?
If we just take a glance at the dog food and the fish food, we can see that their nutrient profile is not very different. But if we dig deeper into the matter, we can see the vast difference between a dog’s food and a fish’s food.
Dogs’ protein requirement is almost 22% (during growth and reproduction) and 18% (for adult maintenance). But for fishes, say a catfish, protein requirement is 28-32%. Lipids make for almost 8% for growing or reproducing dogs and are 5% for adult dogs.
On the other hand, lipids make up almost 7-18% of fish diets. Similarly, the difference in their carbs intake, minerals, and vitamins requirements is pretty visible.
Can A Catfish Eat Dog Food?
No, a catfish cannot eat dog food.
If a catfish consumes dog food regularly for a longer period, it can die at a young age. If you want to feed your fish dog food because of the rising feed bill, then there are a few steps you can choose to reduce your feed bill rather than giving it something which is not suitable for it.
Try and remove the larger fishes so that you can lower the biomass. Then you can further reduce this feeding capacity to two to three times a week during the spring and fall seasons.
You can also reduce the feeding schedule for your pet fishes to three to four times a week. You can follow this strategy from May to September.
What you feed your fish also depends on whether your fish is a herbivore or a carnivore fish. You should not feed your fish when the temperature is below 50F, and if you feed them, you should feed them not more than what they can eat.
If you completely run out of fish food for your pet fish, you can provide your fish with some cooked vegetables such as pumpkin, carrots, peas, cauliflower, etc. Some fishes are also comfortable with eating oatmeal or rice.
