Are goldfish bottom feeders? Do goldfish feed from the bottom of their tank? If so, what food should they eat, and which other types of fish make good companions for this activity?
Well, it turns out that pet goldfish tend to feed from the bottom, right above the substrate – but there are a few essential details you need to know about safe and healthy nutrition for this beloved pet fish!
In this blog post, we’ll look at why gold fish like to feed from the bottom of the tank, what type of fish food is ideal for them
Plus some potential alternatives!, and finally, examine several fantastic species that are suitable tank mates.
Let’s dive in and learn more about caring for your goldfish with proper nutrition – both filtration based and around their munching habits!
Are Goldfish Bottom Feeders?
Yes, goldfish are, in fact, bottom feeders. This is because they naturally search for food near the bottom of the fish tank or water. Goldfish typically feed on algae and other organisms, such as insect larvae and invertebrates, that live on the substrate at the bottom of their environment.
Goldfish have well-adapted mouthparts to help them search for food at the base of a pond or aquarium, usually amongst stones or gravel. They also tend to “mouth” plants that grow near or around them while looking for food particles stuck on some leaves or stems.
Overall, goldfish are known to be omnivorous scavengers by nature, and their diet can often include both plant matter and live prey items found at the bottom of an aquatic environment.
Do You Need a Bottom Feeder with Goldfish?
Yes, goldfish feed from the bottom of their tank, but there’s more to consider regarding their nutrition. You need a bottom feeder with goldfish to help keep the aquarium clean and provide them with additional variety in their diet.
Bottom dwellers are species of fish that primarily scavenge for food at the bottom of an aquarium. They help keep an aquarium clean by consuming residue and other waste organic matter that accumulates on the substrate or walls.
Goldfish are omnivorous, which means they will eat several types of food, including algae wafers and sinking pellets. A bottom feeder can also provide additional variety to your goldfish’s diet by feeding off leftovers from your goldfish’s meals.
Bottom feeders also add activity to a tank and increase oxygenation due to their constant swimming patterns.
Can Goldfish Eat Bottom Feeders?
Yes, goldfish can eat other bottom feeders in their tank. Although small fish such as guppies and shrimp should be avoided, large bottom feeders such as Plecostomus (or plecos) are an excellent food source for goldfish.
Most aquarists recommend feeding them to your gold fish at least once a week or so.
When choosing a suitable bottom-feeding fish for your tank mates, ensure they are significantly larger than the goldfish themselves—at least twice its size. This will help ensure that the smaller species don’t get swallowed up by the bigger ones!
Additionally, consider adding snails and other invertebrates to supplement their diet if you want to provide them with living prey only some of the time.

Numerous species can be great tank mates for your goldfish, so research what would work best depending on the size and setup of your fish tank.
Common bottom feeders like Plecos and loaches work great with gold fish if given appropriate space for both fish species in the same tank.
Natural Habitat for Goldfish
Goldfish, also known as Carassius auratus, is a cold water fish species originating from East Asia. They prefer slow-moving water in temperate climates and can usually be found in rivers, ponds, and lakes.
Goldfish mainly occupy fresh inland waters and wetlands in temperate regions worldwide.
In the wild, they feed on tiny aquatic organisms such as insect larvae, crustaceans, worms, and vegetation.
In captivity, goldfish can be fed various floating food such as store-bought pellets, flakes, and freeze-dried treats. They also accept live foods such as worms, daphnia, and brine shrimp.
How Often Do You Feed Goldfish?
Goldfish need to be fed daily, but it’s important to feed them appropriately. Their diet should consist of various foods to get the necessary nutrients.
It is generally recommended that goldfish be fed two meals daily, with each meal consisting of no more than what they can consume in two minutes.
It’s essential to keep an eye on your goldfish and ensure they are not overeating. If you notice that there is still food left after two minutes, you should reduce the amount of food given at each meal.
Goldfish are natural scavengers, so they also look for food particles stuck on some leaves or stems. They may even try to round them while looking for fish food.
Therefore, it’s vital to ensure your bottom feeder fish tank is regularly cleaned and maintained to provide a healthy environment for your goldfish.
Remember: Goldfish may unintentionally gulp air while feeding at the surface, causing them to lose balance and flip upside down. To prevent this feeding goldfish issue, take care when providing food – soak flake foods briefly before serving and opt for non floating food pellets.
