    Tetra Tropical XL Color Granules

    Guaranteed Analysis:

    Protein: 5%

    Fat: 5%

    This color-enhancing granule food from Tetra seems to be the best option for color-enhancing tropical fish.

Tetra tropical color granules have a noticeably high amount of protein, which can be used to enhance a rasboras color and speed up the growth process of young rasboras.

    Pros
    • High color-enhancing ability
    • Clear-water formula
    • Extreme color enhancer

    Cons
    • May cause constipation
    • Contains a lot of filler


    7. Aqueon Tropical Granules Fish Food

    Aqueon Tropical Granules Fish Food

    Protein: 41%
    Fiber: 3%
    Fat: 7%

    Aqueon Tropical Granules is a highly digestible fish food that does not cloud aquarium water. The granules are sufficient in providing balanced and fortified ingredients for the health of small tropical fish. It does cloud the water if it has not been eaten by the fish within a few minutes, although this should be unlikely if you feed your fish an appropriate portion of food.

    According to the ingredients list, it contains several fillers like fish meal and soybean meal which have little nutritional value. It also has copper sulfate inside which can be harmful to invertebrates that may find this food in the aquarium. However, it is a decent tropical fish food that is safe for rasboras and has plenty of nutritional benefits.

    Pros
    • Highly-digestible pellet
    • Balanced ingredients

    Cons
    • Contains fillers
    • May cloud water


    8. A.D.P No.2 Powder Type Tropical Fish Food

    A.D.P. No.2 Powder Type Tropical Fish Food

    Protein: 60%
    Fiber: 1%
    Fat: 10%

    This tropical fish food has the highest amount of protein out of all the reviewed foods. This makes it a good choice for breeders who want to feed their rasboras a higher protein-rich diet to encourage spawning or to raise fry and young rasboras that you want to grow out quickly. This is a micro pellet that does not cloud the water with leftover food sediment. It contains 60% protein with added vitamins and minerals to keep your rasboras healthy.

    This formulation helps fish larvae and fry have a higher chance of survival as it is a complete diet for them and aids in healthy growth and development. Since it is better suited for breeding adults, larvae, and fry, it should not be used as a staple diet since the high protein content and low fiber can cause issues over time.

    Pros
    • 60% Protein
    • Does not cloud water
    • Aids in growth and development

    Cons
    • Not a good staple food
    • Better suited for fry


    9. API Tropical Mini Pellet

    API Tropical Mini Pellet

    Protein: 37%
    Fiber: 5%
    Fat: 8%

    The API Mini Pellet is perfect as a daily commercial food for rasboras. It sinks quickly but rasboras can chase the pellet till they catch it to eat. This would also mean that you should not overfeed the pellet as the leftover sinking pellets can get lost at the bottom of the tank and start to foul the water.

    API contains high-quality proteins like shrimp and squid which are good for fish growth. It also helps fish absorb nutrients readily which results in less waste. The seafood flavor is enticing for rasboras, and garlic has been added to make it more appealing to fish.

    Pros
    • Safe as a daily food
    • Appealing flavor

    Cons
    • Sinks fast
    • May cloud water

    The King Fish Tropical food has been formulated to be a 45% protein-rich granular food with high amounts of spirulina for growth and color enhancement. It is suited for all ages and sizes of rasboras and can be fed as a long-term diet. It should be noted that the food is on the lower end and some of the ingredients are questionable.

    It also seems to have quite a few fillers which are not useful for fish. However, it can make decent food for rasboras. It is a color enhancer and the ingredients do not cloud the water. The color-enhancing ingredients have been known to increase the vividness of a rasboras color while keeping them healthy and increasing their lifespan. This food may have its drawbacks, but it shouldn’t be overlooked.

    Pros
    • Protein-rich
    • Color enhancing

    Cons

    • Low-quality ingredients

    wave tropical dividerBuyer’s Guide: How to Purchase the Best Rasboras Food

    What Makes An Ideal Food for Rasboras?

    Rasboras should have a diet that consists of plant and protein-based materials. They are omnivores and naturally eat these foods in the wild. In captivity, you should be aiming to provide them with a diet that closely replicates the food they would eat in the wild, but in a more concentrated form like a pellet. If possible, you should avoid feeding rasboras and other types of fish flake foods. It starts to dissolve as soon as it gets wet.

    This not only lowers the number of nutrients your rasbora will receive, but it can cause water issues like clouding or ammonia spikes. Flake foods are also typically colored with harmful dyes that are not useful to fish. You should aim to feed your rasbora a small pellet or granular food. These seem to be of higher quality and do not leach nutrients into the water right away. The food should have over 30% protein, 2% fiber, and 4% fat to be nutritionally balanced for rasboras.


    Factors to Consider Before Buying Rasbora Fish Foods

    Factors
    • Age: Fry and adult rasboras will have different nutritional requirements. Young fish should have higher amounts of protein in their diet and can tolerate a much smaller fat and fiber percentage than adults. If you are planning to breed your rasboras or raise fry, you should opt for a food that has between 45% to 65% protein.
    • Size: Adult rasboras can eat larger pellets that smaller fish may struggle to eat. Granules seem to be the better option for young rasboras, and they can easily fit into their mouth.
    • Amount: Tropical fish should be fed around 2 to 3 times a day and only as much as they can consume in 2 minutes. If you have large shoals of rasboras, they will require more food. You should look for a brand that has larger containers of food available so that you do not have to buy food regularly.
    • Aquarium size: If you have a smaller aquarium, you should avoid foods that foul the water. This can quickly make the water toxic to the fish after and few feedings. Make sure the label claims that the specific food does not cloud the water.
    • Other tank mates: Some foods that have copper can be very harmful to shrimp and sensitive snails. Although copper sulfate is usually last on the list and found in small amounts, if your invertebrates eat the leftovers regularly, they can poison themselves. If you have a betta with your rasbora, you must ensure they do not eat too many tropical fish flakes since plant matter is difficult for them to digest.

    Best Foods in This Category

    The best food for your rasbora depends on the size, age, and health. There is no one specific food that is ideal for every rasbora, so it is important to take a look at what the different brands have to offer.

    Best Foods in This Category:

    What Ingredients Should You Avoid?

    It is recommended to avoid foods that contain too many fillers and additives. They do not offer valuable nutrition to fish and are used to increase the volume but lower the quality of the food. Try to avoid copper sulfate if you have invertebrates with your rasboras.

    The main ingredients should be of high quality, and not wheat flour or wheat germ. Spirulina, shrimp, squid, algae, and garlic are good ingredients in fish food. Remember that the ingredients at the top of the list are the most concentrated in the food, and the last items on the list only occur in small quantities.
