[vc_row][vc_column][vc_column_text]Everyone loves a good meal. Great food will always make your day better, whether it’s your mom’s homemade lasagna or that pizza from down the block. But it’s easy to get tired of even the best meal every day. You want different things, but did you know that your fish want the same things? Also, what do fish eat?
There’s no singular answer to this question because every fish is different. What do goldfish, koi fish, and betta fish eat? Just like you, your grandmother, and your best friend all have different food preferences and nutritional needs, so do your fish. Various fish species prefer certain foods and have unique dietary requirements that affect what you should feed them.
Ready to find out what food is your fish’s equivalent of mom’s homemade lasagna? Let’s dive in…[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]
Processed dry food is a solid choice for many different species of freshwater and saltwater fish. As they come in many forms, sizes, and shapes, there is something under this umbrella for almost every animal in your tank.
“What do fish eat?” If you’re like most people, your mind jumps straight to fish flakes. These are often portrayed in movies, television shows and cartoons as a little shaker that drops food.
Flakes are the most common type of fish food and the easiest to use. They’re small, flakey pieces you sprinkle into the aquarium a pinch at a time. The top feeders will swim right to the top of the aquarium to eat it up.
But not all fish flakes are the same. It’s important to note what flakes you feed your fish. Because saltwater and freshwater fish have different nutritional needs, you should feed marine flakes to saltwater fish and tropical flakes to freshwater fish. Along with those general-purpose flakes, there are also ones made just for certain species, like cichlids and goldfish, so check to see if your fish needs something similar.
How much flakes do fish eat? The answer isn’t always clear, but it’s safer to be safe than sorry and not feed them too much. A little bit goes a long way with your aquatic friends.

In addition to flakes, there are also wafers, which are bigger and heavier. These are appropriate for larger fish, who have more significant appetites and nutritional needs. You may switch to wafers from a flake diet as your fish grows. You may also choose to offer both types of food. After all, even your fish enjoy variety in their diets!.
Wafers are also an excellent choice for feeding bottom feeders in your tank. Wafers will sink to the bottom of the aquarium because they are bigger and heavier, but flakes will stay on top because they are so small.
Pellets are typically somewhere between fish flakes and wagers. Some float, others sink quickly, and yet others sink slowly. Some even stick to the glass on the side of the tank, providing food for middle-feeders.
You should feed your fish different kinds of processed food depending on whether they live in saltwater or freshwater, how big or small they are, and where in the aquarium they eat. You also need to consider the basic nutritional balance your fish requires. For example, carnivorous fish require diets consisting of 45-50% protein, while herbivorous fish require far less.
If you want to know “What do fish eat?” you should do a lot of research on your specific fish. Then, make a feeding plan that helps all fish species get what they need to grow and be healthy. [/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text].
The ocean is filled with an incredibly diverse range of fish species, each with their own unique diets. But have you ever wondered – what exactly do fish that live in the ocean eat? Their dining habits may surprise you!
As an avid scuba diver and ocean lover, I’ve spent countless hours underwater observing fish in their natural habitats. Through my experiences and research, I’ve learned that ocean fish have adapted to eat a wide variety of foods depending on where they live and what’s available.
In this article, we’ll explore the major categories of ocean fish diets, what specific species eat, and how their feeding patterns impact the underwater ecosystem. Let’s dive right in!
Herbivorous Ocean Fish – Plant Eaters
Believe it or not, some fish actually consume aquatic plants and algae as their main food source. Fish with this vegetarian diet are known as herbivores.
Some common herbivorous fish found in oceans worldwide include:
-
Parrotfish – Use their beak-like jaws to graze on algae coating coral reefs Their feeding helps keep reefs healthy
-
Surgeonfish – Feed on algae and weeds. Some have a scalpel-like spike on their tail for protection from predators.
-
Rabbitfish – Use their sharp incisor teeth to bite off chunks of algae and seaweed. Often found in schools grazing together.
-
Ocean sunfish – The world’s largest bony fish. They gulp in huge amounts of jellyfish and zooplankton.
Herbivorous fish play a critical role in aquatic ecosystems by regulating algae growth and providing food for larger carnivorous fish.
Carnivorous Ocean Fish – Meat Eaters
The most stereotypical image we have of ocean predators are carnivorous fish. Equipped with sharp teeth and lightning-fast speed, these fierce hunters feed on other fish, squid, crustaceans, and basically anything they can capture.
A few carnivorous fish found roaming open oceans include:
-
Barracuda – Fierce predators with razor-sharp teeth. They use camouflage to ambush smaller reef fish.
-
Marlin – Legendary sport fish with spear-like upper jaws. Feed by slashing through schools of smaller fish.
-
Tuna – Powerful swimmers known for their sense of smell to detect prey. Consume fish and squid.
-
Sharks – The apex ocean predators. Utilize teeth and keen senses to hunt fish, marine mammals, turtles, and more.
Carnivorous fish are vital for keeping ocean food webs balanced by preying on weaker individuals and preventing overpopulation.
Omnivorous Ocean Fish – The Best of Both Worlds
Next up are omnivorous fish with the unique ability to consume both plant and animal matter. This provides flexibility in their diet if certain food sources become scarce.
Some omnivorous ocean fish include:
-
Snapper – Opportunistic feeders eating crabs, shrimp, mollusks, and seaweed.
-
Salmon – Born in freshwater but migrate to saltwater oceans to mature. Prey on smaller fish but also consume plankton.
-
Trout – Dwell in shallow coastal regions. Feed on krill, plankton, squid, small crustaceans, and aquatic insects.
-
Tilapia – Versatile fish adapting to varied plant or animal-based diets depending on habitat.
The adaptability of omnivorous fish enables them to thrive in changing environments and prevents food chain disruption if certain resources decline.
Unique Ocean Fish Feeding Strategies
Ocean fish have evolved some fascinating methods for capturing their next meal. Here are a few unique examples:
-
Dragonfish – Use bioluminescent lures to attract prey in the pitch-black deep sea.
-
Hagfish – Bore holes into dead carcasses to feast on decaying remains.
-
Bat rays – Sift through sandy bottom sediments sucking up buried clams and crabs.
-
Fangtooth – The deepest living fish using glow-in-the-dark teeth to attract and trap prey.
-
Mola mola – Massive ocean sunfish sucking in entire schools of jellyfish.
Observing these unique feeding mechanisms in action allows marine biologists to better understand the behavioral adaptations of ocean fish.
Common Ocean Fish Food Sources
Now let’s examine some of the most common food sources found in ocean fish diets:
Plankton
Microscopic plankton including phytoplankton, zooplankton, fish eggs, and fish larvae form the base of open ocean food chains. Tiny shrimp-like krill are particularly important prey.
Algae
Algae like giant kelp provide food and shelter for fish dwelling near coastal reefs and kelp forests. Omnivorous fish graze directly on the algae.
Squid, Octopus, Cuttlefish
Cephalopods are eaten by many open ocean carnivorous fish attracted to their soft bodies rich in protein, fats, and amino acids.
Crustaceans
Crabs, lobster, shrimp, and other crustaceans are a major food source due to their abundance near ocean floors and coral reefs.
Small fish
Large predatory fish readily feed on smaller schooling fish like herring, anchovies, and sardines that congregate in massive numbers.
Fish eggs
Nutrient-rich fish eggs from species like cod, mackerel, and capelin are devoured by opportunistic egg predators.
As you can see, ocean fish have adapted diverse diets to take advantage of various food sources that become available depending on local conditions.
Impacts on Ocean Ecosystems
The feeding behaviors of ocean fish have cascading effects throughout the underwater environment. Here are some examples:
-
Overfishing apex predators like tuna and billfish can cause prey fish populations to spike, disrupting food webs.
-
Loss of herbivorous fish can cause harmful algal blooms from unchecked growth of phytoplankton.
-
Preserving baitfish like anchovies and menhaden supports populations of birds, marine mammals, and commercial fish.
-
Introduced invasive species can compete with native fish for limited food resources.
Careful management of ocean fish stocks and protection of critical habitats maintains balance across marine ecosystems.
Well, I hope you enjoyed this deep dive into the many underwater dining options for ocean fish! Observing their unique feeding habits and food sources in the wild fosters awe and respect for the diversity of our oceans. Next time you eat a filet of fish from the seafood counter, consider the intricate aquatic food web that brought it to your plate!
Live and Live-Like Foods
Fish don’t always need processed foods to stay healthy. Sometimes they need something that tastes like wild fish they might catch. You have a few different options for addressing this.
Freeze-dried organisms such as krill, bloodworms, plankton and similar make for a great dietary supplement. They provide lots of nutrition and flavor for your fish. An additional benefit of freeze-dried foods is that they’re less prone to transmitting disease than live foods like feeder fish sometimes do.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_single_ =”5124″ img_size=”full” add_caption=”yes” alignment=”center” css=”.vc_custom_1711662964591{padding-top: 20px !important;padding-bottom: 20px !important;}”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]
Frozen foods are another option to consider. These include whole frozen organisms such as krill, brine shrimp, mysis, silversides, earthworms, chopped frozen clams and squid. There are even frozen food mixes specially formulated for species such as sharks and discus.
An advantage of frozen foods is that they’re closer to what fish eat in nature. This can help stimulate the appetites of fish that are rejecting other types of food.
If this doesn’t work, you may consider using a live feed. This can make a new animal that won’t eat other food in its new environment act out its natural predatory instincts.
This might mean crustaceans such as crayfish. These are best purchased from bait shops, as wild ones may contain traces of pollution they’ve encountered, including pesticides, herbicides and fungicides. You should go for the small ones whose claws won’t injure your fish.
When you ask yourself, “What do fish eat?” you might also think about bugs like mealworms, crickets, and more. Again, avoid wild ones, which may make your fish sick. You can feed them fish flakes or other foods that are high in nutrients that will be passed on to your fish if you want to.
You can also get a lot of other animals at bait shops that you can use, like earthworms, snails, slugs, caterpillars, and more.
Then there are feeder fish. Whether or not you use them is your decision, as there’s debate around whether it’s necessary or beneficial. If you do use feeder fish, there are a few rules to remember:
- Don’t feed saltwater fish feeder fish from freshwater fish, or the other way around. This is bad for you nutritionally and can lead to health issues like liver disease.
- Don’t use store-bought feeder fish. These animals live in dirty tanks and aren’t always well taken care of. Because of this, they can give your fish a lot of different diseases and parasites. If you use feeder fish, breed your own.
- Don’t eat too much—most fish only eat other fish as a supplement, not as a main food source.
Regardless of what you decide about live fish, though, there is one thing you can be sure of: don’t feed beef heart to your fish. While this used to be recommended, it’s no longer considered advisable because the steroids used to raise cows can cause health problems in your fish.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]
Other Treats for Herbivorous Freshwater and Saltwater Fish
For the vegetarians in your aquarium, there are other foods you can use to give them some variety.
Spirulina, for example, is a very healthy algae that is great for both saltwater fish like clownfish and tangs and freshwater fish that eat plants. Seaweed is available in dried sheets and is appreciated by plecos, cichlids, and tangs. Romaine lettuce leaves, frozen peas, lima beans and cucumber slices are popular fish treats among appropriate species. [/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text].
