5/5 - (3 votes)

Aquarium fish are a special pet as they inhabit a self-contained environment, and you cannot interact with them directly. Having said that, owning a home aquarium brings in a range of enormous benefits over other pets. 

Keeping a home aquarium has been proved to lower stress and reduce blood pressure, and you’ll have a certain sense of satisfaction from creating, designing, and maintaining a thriving aquatic ecosystem in your space.

Like any pet, aquarium fish need a balanced diet to grow. What most people do not know is that different species have different nutritional needs. Our post today will help you find out the best fish food that will offer beneficial vitamins and minerals to your beloved pets.

Types of Fish Food 

Fish Eating Food

Before identifying the best food for your fish, let’s figure out how many types of fish food are available to choose from. 


Fakes are great for feeding mid-water and surface-feeding fish. Fish flakes are often made from dehydrated ground ingredients, which are spread paper-thin and baked. Since the flakes will be soaked, they drop to the bottom, where fish living in that area can eat them. 


Pellets are tiny sticks or balls of dehydrated fish food. Pettlets can have various sizes to fit different fish species and can be floating or sinking. 

Sinking wafers 

Wafers are disks of fry food that are produced to sink to the bottom. This type of food is suitable for catfish, plecos, and other bottom-dwellers. Wafers are often regarded as “algae” waters; however, they often don’t include much algae and are generally of poor quality. 

Gel food 

Gel can come in a powder that you can combine with hot water to make a stiff jelly-like substance. You can also buy pre-made gel in small plastic tubes that you just need to squeeze into the aquarium. Gels are quite expensive, but your fish will love them as a treat. 

Free-dried food 

Freeze-dried food often contains bloodworms, brine shrimp, and so on. This food is a good source of meaty protein. 

Frozen food 

Frozen food are daphnia, brine shrimp, bloodworms, mosquito larvae, etc., that are flash-frozen into cubes. 

Live food

Live food, including brine shrimp, daphnia, and bloodworms, are loved by fish, particularly predatory species which are natural-born hunters. Besides, you can buy “feeder fish” like goldfish, guppies, or minnows to feed larger predatory species. 

However, the downside of live food is that it might come with unexpected extras such as bacteria and parasites that could be harmful to your fish.

This product is freeze-dried to maintain nutritional quality, and they don’t have detrimental parasites or bacteria. 

People might not think of aquarium fish as carnivorous, but most of the species are. Tetras, discus fish, and betta fish are all examples of fish requiring a carnivorous diet from meat-based food such as worms and other insects. One of the most popular fish food picks for carnivores is Hikari Bio-Pure Freeze-Dried Bloodworms. 

Bloodworms are similar to mosquito larvae, and they are one of the most common foods for carnivorous species of fish. Nevertheless, the issue with this type of food is that they are usually harvested from waters polluted with parasites.

12. Omega One Veggie Rounds

High in plant-based protein from fresh-harvested kelp, Omega One Veggie Rounds seem appealing to a number of herbivorous fish. 

Herbivorous species of aquarium fish need a plant-based diet, but this doesn’t mean you don’t feed them protein. Kelp is a good protein option for plant-eating tank fish, provided that it is harvested from a reliable source. 

Omega One Veggie Rounds have three different sizes. Formulated with fresh-harvested kelp and fortified with omega fatty acids and other healthy nutrients, this food appeals to a range of freshwater and saltwater fish. Plus, these sinking wafers work well for bottom-feeders and won’t make your tank water cloudy. 

However, wafers may not always sink fast, and you should remove uneaten food after an hour to avoid breakdown. 

13. Omega One Shrimp Pellets

Bottom swimmers like Corydoras catfish have a vital role in the home tank by digesting the leftover fish food that drops to the bottom of the aquarium. Therefore, bottom dwellers help save the water column free from detritus and control ammonia levels by eating extra food before it breaks down. 

Bottom fish will consume leftover fish food and other debris while they still require a balanced diet. Formulated with fresh shrimp and other whole food ingredients, Omega One Shrimp Pellets sink fast to bring a nutrient-sufficient diet to bottom feeders. 

A decent type of fish food for bottom swimmers must meet two requirements. It needs to sink fast, so other fish do not eat. And it needs to contain abundant nutrition. Omega One Shrimp Pellets are manufactured with fresh whole shrimp, cod, salmon, and herring to offer a protein-rich diet for bottom-feeding fish. In addition, this product is supplied with natural fats and various color-enhancing vitamins and minerals. 

14. New Life Spectrum’s Marine Fish Formula

Filled with numerous whole food ingredients, the recipe is highly focused and appealing to a host of marine fish. This product is packed with quality ingredients such as Ulva seaweed, whole Antarctic krill, spirulina, and omega-3 fish oil to offer a balanced diet for your fish.

15. Hikari Algae Wafers

This recipe is scientifically designed for algae-eaters and other herbivorous fish.

If your tank has an issue with algae growth, you might think of introducing an algae-eating species of fish like Plecostomus to your aquarium. Bear in mind, however, that most fish will need supplemental feeding. Algae Wafers are a great source of supplemental nutrition for algae-eating fish and other omnivorous bottom-feeders and the go-to choice is Hikari Algae Wafers. 

Hikari Algae Wafers are created from a mixture of premium algae and proteins for balanced nutrition that benefits omnivorous species of fish. Whereas this food is tailored for Plecostomus and other bottom-dwellers, mid-level fish and even some surface swimmers can pick at the wafers. They are variously sized so that they don’t swallow whole. Moreover, they also sink fast so they won’t be eaten before your bottom-swimmers can get to them. 

However, it is still not recommended for surface feeders and you should remove the uneaten portion after two hours. 

Why Should You NOT Overfeeding Your Fish?

Why not overfeeding fish?

Cloudy water 

Uneaten food often decomposes in the substrate, gradually causing the water to become cloudy and polluted. 

Low oxygen levels 

As eaten portion and fish waste decompose, the process uses oxygen while producing CO2. This aerobic mechanism shows that there will be less oxygen in the water for your fish to breathe. 

Algae growth

Overfeeding is the top cause of redundant algae growth in fish ponds and aquariums. Since fish are overfed, huge quantities of dissolved nitrates, phosphates, and organic material accumulate in the water, stimulating algae to grow. 

Mold and fungus

Similar to algae, mold, and fungus will boom if there is a large amount of organic material in the water. Therefore, if you find cottony, fluffy white growth on your plants or substrate, that’s a sign that you might be overfeeding your pets. 

Planaria worms 

If you notice some tiny white or tan-colored worms crawling up your tank glass, that’s a good indicator that your water quality has some problems. 

Blocked filter media

Your filtration system is made to filter waste from the water and process them into less detrimental substances so that the environment remains safe for your pets. 

Nevertheless, overfeeding can lead to too much waste to collect on the filter media. Besides, the filters might get clogged, so they won’t work effectively. In other words, the water flow through the tank is decreased, and the water quickly begins to turn dirty and toxic. 

High ammonia and nitrites 

As uneaten food and fish waste break down, they produce ammonia and nitrites that are harmful to your fish. Even though your filter system processes these chemicals, you might overload the filter and pollute the water if you overfeed your pets.

Low pH levels 

Decomposing organic materials decreases the amount of oxygen in the water and reduces the pH because acids are released during the process. 

Each fish species has a specific pH range, and those that require a more alkaline environment might get stressed if the pH is out. Stress is extremely harmful to your fish as it can affect their immune system, leaving your pets prone to diseases and parasite infections. 

Wrapping Up! 

Seeking and feeding proper fish food is substantial to the health and upkeep of your fish. Good food can guarantee a balanced diet, improve the colors and bolster your fish’s immune system. 

Make choices based on the species of fish you keep, as well as their size and the number of species you get in your aquarium. Keep in mind that some fish are bottom feeders and others surface swimmers. You should ensure that you provide food satisfying the requirements of the individuals and the group as well.
