Buyer’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
- 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.
