Here as well, the freshwater fish are different and the same goes in contrast. The geographic location also matters. We will let you know the most common foods eaten by the most common fishes.
What Do Fish Love to Eat?
Normally, the bigger fishes are supposed to eat the smaller ones, which is true to some extent because not every large fish likes to eat smaller fish. They are just specific species that are commonly found in deep and warm oceans. However, this isn’t the case with the warm and cold water fishes of rivers and streams.
The fish that rely on other fishes and their meat are called carnivores. Omnivores are those fishes that have a wider tooth and they are formal to eat anything they get from meat to plants and insects. Freshwater fishes could contain some omnivores. Herbivore fishes on the other hand are supposed to eat only herbs, vegetables, and plants. Aquarium fishes are carnivores by the way.
As long as river and edible fishes are concerned, a majority of them love to eat insects, worms, and smaller fishes along with some herbs as well. A big percentage of their diet is based on protein content and this is why fishes are one of the best sources of protein for gym lovers and people who want a healthy diet. Salmon, Rohu, Trout, and Tuna also belong to this landscape that is widely eaten.
1. Zooplankton & Phytoplankton
The main portion of their diet comes from Zooplankton and phytoplankton which are sort of microorganisms found under the water. Zooplankton isn’t just exclusively eaten by Salmon or trout, they are also a common diet of many other fishes including sharks and whales. Zooplankton themselves are fed on algae which is also a great dish for many fishes of the family that we usually eat.

This is also common that a larger fish would take a larger meal to get the best of its nutritions. Now, that food also depends on various factors that mainly include biological factors along with geographic positions other than the size of that fish. The environment of a specific region also plays a significant role in their diet.
As Salmon are carnivores, they are required to take a protein-rich diet throughout the day. Depending upon one’s case, Salmons can eat both dead and live meat to fulfill their needs. This could be obtained from fellow fish and insects along with a small number of plants as a good source of energy.
2. Worms & Insects | What Do Fish Eat
Worms and insects like flies, crickets, or grasshoppers play a significant role in the diet of a fish as all these things are a good source of protein. Now, there are also a variety of worms or insects found under the water, but they can’t all be eaten by fish as some worms can be harmful and can carry some diseases also.

However, bloodworms are some of the favorite and healthiest range of worms for fish to include in their diet. But, quality checks and observations are still necessary even for those worms before feeding them to fish. Now, depending upon the type of mood of a fish, worms or insects could be dead or alive.
Living worms are better to feed as they are fresh and there is a very little loss of nutrition compared to dead worms and insects. Again, not all insects can be eaten alive especially if they are bigger in size or insects of some specific species. Some worms can also be grown in your home for your pet fish. It is also a good idea to ask your local pet store what to and what not to feed.

Technically, algae are used as a pigment in fish ponds that plays a key role to generate oxygen and control the carbon content. Salmons are a big fan of algae and their flash is usually in a pink or orange shade mainly due to algae that help them stay healthier and also in the digestion of food.
Sponges on the other hand are useful to filter the water in the aquarium for your pet fish. But, not all sponges could be used for your fish as they could turn poisonous for your fish instead of filtering. In any case, you should never make these two things responsible for taking care of your fish. Always give diverse food to your babies along with flake foods as well.
