Can Goldfish Eat Betta Food

Can Goldfish Eat Betta Food

Two of the most common species for first-time fish owners are Betta and Goldfish. But the truth is they’re quite different from one another. Some individuals might think that a fish is a fish and any food os good, but what will happen if Goldfish eat Betta food or if you feed Betta food to a goldfish?

A goldfish can eat Betta fish food occasionally as one of the best ways to get their protein requirements, but it should be provided sparingly and used as a special treat for your Goldfish no more than once weekly. Goldfish like to eat food that has sunk to the bottom or middle of the aquarium, so if you do offer Betta fish food, the Goldfish will not eat it until it sinks.

Monitor this very carefully, because any meal that settles on the bottom of the tank can break down and cause ammonia levels to rise.

Difference in the Diet of a Goldfish and a Betta

Before explore whether or not a goldfish can eat Betta fish food, let’s take a look at what the diets of each of these fish consist of both in an aquarium and in the wild. Bettas are carnivores. In the wild, however, they will eat just about anything from worms to insects to smaller fish.

Protein makes up as much as 70 percent of their intake in the wild. To try to replicate this, most commercial Betta food entails about 55 percent protein. On the other hand, Goldfish are omnivores and require both vegetables and protein in their diet.

The digestive system of Goldfish works differently than a Betta’s, and too much protein can cause problems, including swim bladder disease, gas, and even kidney failure if they overeat.

Goldfish Feeding

A goldfish doesn’t have very peculiar eating requirements, or at least not as specific as the Betta. Goldfish are omnivores — which means that they eat both plant and meat-based matter too. Goldfish don’t require much protein in their diet, and in fact, can survive on lower levels of protein than many other fish.

Goldfish need a good mix of protein, nutrients, and vitamins, and as well as many fiber too, with protein intake only needing to be around 25 percent of their overall diet. Generally, generic flaked goldfish food is more than enough to keep them excited. Also, you do want to mix it up a little with live foods, flakes, freeze-dried foods, and some fresh food too.

The main point is that Goldfish aren’t very picky, and as long as they have a balanced diet, they’ll be just fine. All of that being said, Goldfish can eat betta food occasionally, yes, but not too much. Betta has some pretty specific dietary requirements, and their meals are rich in protein.

A betta’s food will be too high in protein for Goldfish to eat all of the time. Additionally, Goldfish prefer their food to sink to the bottom or even the middle of the fish tank as aforementioned, which, as you’ll see, is not the same with the betta fish.

Betta Fish Feeding

Betta fish, on the other hand, are carnivores and insectivores, meaning that the vast majority consists of proteins and meat. In simplest terms, however, a betta needs to have a diet that contains 55 percent protein at the very least. Anything under 55 percent protein is no good, and ideally and seriously speaking, around 50 to 60 percent protein is the best.

As you can see, a betta’s diet needs to consist of a whole lot more protein than a goldfish’s diet. Betta prefers to eat a mix of high protein foods like blood worms,  pellets, daphnia, brine shrimp, and other small meaty creatures. Moreover, the betta fish prefers to eat its food while it’s floating near the top of the tank, that is why betta fish food is often designed to float near the top of tank, unlike goldfish food, which tends to sink deeper middle or down into the tank.

Can Goldfish Eat Bloodworms

The answer is absolutely yes, it can eat bloodworms, but only to a certain extent. Primarily, Goldfish are herbivores, but also they do eat some plants. Goldfish do need a little bit of animal-based protein in their diet – which makes bloodworms the right choice for them. You can supplement your Goldfish’s meal or snack time with a few bloodworms.

Just ensure not to feed Goldfish with bloodworms more than twice per week, as they do require a lot more plant-based food than meats. Alright, keep in mind that you probably want to go with freeze-dried bloodworms.

Live worms are also an option, but they can harbor diseases and parasites that can make your Goldfish quite ill. The freeze-drying process assists in eliminating these dangerous parasites and diseases.

Can Goldfish Eat Betta Pellets

Okay, so it’s not like you are going to kill your Goldfish if you give it Betta food on occasion, but definitely, it is not recommended to be done very often. Replacing your Goldfish’s regular good with Betta meal can be done at most once in a week.

Betta eats a lot more meat-based protein than Goldfish, which means that Betta pellets have a much variant nutritional makeup than Goldfish food. Betta fish food is too high in protein to be feeding it to Goldfish very often.

Use it as a one-off food replacement if you happen to run out of goldfish food, but no more than once in a week at the very most.


The bottom line or fact is that Goldfish can eat some betta food, but not too much because the protein levels are just too high and might harm your Goldfish. At the same time, goldfish food does not nearly have enough protein to support a healthy betta fish. While each fish can eat the other’s food on very rare occasions, therefore, it’s not recommended. Both the Goldfish and betta fish should be fed food that is specific to their needs.
