The Fluval Bug Bite range is a collection of premium fish food products formulated to provide a nutritious everyday feeding solution for insectivore fish.

Bug Bites contain higher protein levels than other fish food products, along with plenty of vitamins and minerals, offering a highly nutritious option for your fish.

I have tried the following three products from the Fluval Bug Bite range and will focus on my experiences with them:

  • Fluval Bug Bites Tropical Granules
  • Fluval Bug Bites Bottom Feeder Granules
  • Fluval Bug Bites Tropical Flakes

In my experience, the granules are definitely the better option, and all of my fish absolutely love them. However, some of my fish won’t eat the flake formula.

Other formulas in the range that I have not tried, but that may be a better fit for you, include:

  • Fluval Bug Bites Cichlid Formula
  • Fluval Bug Bites Color Enhancing Granules
  • Fluval Bug Bites Goldfish Granules
  • Fluval Bug Bites Pleco Formula
  • Fluval Bug Bites Spirulina Flakes
  • Fluval Bug Bites Algae Crisps

Most formulas are available in multiple granule sizes, so always consider the size of your fish when choosing Bug Bites. This ensures the food fits comfortably in your fish’s mouth.

My photograph below shows the difference in granule size between the bottom feeder granules (0.14cm-0.2cm) and the small tropical granules (under 0.14cm).

Fluval Bug Bites are a premium fish food formulated with high-quality ingredients designed to provide optimal nutrition for a wide variety of fish species.

The primary ingredient in Bug Bites is sustainably processed black soldier fly larvae, which offer several benefits for your fish. Black soldier fly larvae are an excellent source of protein, making up around 40% of the content in Bug Bites.

This high protein content is crucial for the growth, repair, and overall health of your fish. Protein is especially important for young, growing fish and species that have high metabolic rates. The amino acids in these larvae help support muscle development and ensure your fish maintain a strong, healthy body structure.

In addition to protein, Bug Bites contain other essential nutrients. For instance, they include omega-3 and omega-6 fatty acids, which are vital for maintaining a healthy immune system, promoting vibrant colors, and ensuring proper development of fish scales and fins. These fatty acids also support cardiovascular health, aiding in the overall well-being of your fish.

Flakes Vs Granules

Fluval Bug Bite Flakes And Granules

Fluval Bug Bites are available as flakes or granules, and my fish definitely prefer the granules over the flakes.

This preference might be due to my fish being accustomed to granule or pellet foods instead of flakes, so you might have a different experience with your own fish.

Many of my fish won’t even consider the flake formulas of Bug Bites, but they instantly come to the front of their tank to feed on the granules.

I have tried crushing both the flakes and granules into tiny fragments, thinking the issue might be the size, but my fish still preferred the granules over the flakes.

If you’re looking to test Fluval Bug Bites with your own fish, I recommend starting with a small granule formula rather than the other options.

Larger fish can easily eat small granules, while smaller fish might struggle with larger granules. Opting for a small granule formula allows you to test the product with a wider range of fish.

What Fish Can Eat Fluval Bug Bites?

Fluval Bug Bites are suitable for a variety of fish, including betta fish, goldfish, guppies, tetras, Corydoras, and plecos.

Here are the fish I currently keep that really enjoy eating Fluval Bug Bites:

  • Neon Tetras
  • Honey Gourami
  • Guppies
  • Corydoras
  • Chili Rasboras

The Corydoras and Honey Gourami both eat the regular granule size, but my guppies prefer the microgranule size due to their smaller mouths. Guppies tend to wait for the Bug Bites granules to soften in the water and then eat them regardless of granule size, as the softer, water-soaked texture allows them to tear off small portions easily.

My neon tetras can sometimes eat the smaller microgranules, but I prefer to crush the Bug Bites into tiny particles for my tetras and rasboras.

As I mentioned in my article on chili rasbora foods, there are several ways you can crush your Bug Bites to make them smaller for your fish.

The easiest method I’ve found is to put the Bug Bites into a cheap pepper grinder and grind them up, just as you would with pepper for your own meals.

Adjusting the pepper grinder to crush the Bug Bites to the appropriate size can be tricky, but spending a few minutes tweaking the dial on the top of the grinder is usually enough to get it set up correctly.

My neon tetras and chili rasboras definitely prefer their Bug Bites in this crushed, tiny size over the standard size directly from the tub.

If you are keeping smaller fish in your tanks, I highly recommend this method.

How Often To Feed

I usually feed my fish twice a day, once in the morning and once in the evening, with Bug Bites typically making up one of these meals.

However, feeding frequency can vary depending on several factors:

  • Type of fish
  • Aquarium size
  • Stocking levels
  • Bug Bite formula
  • Size of the Bug Bites
  • Other foods added
  • Natural foods like algae

Many aquarists remove any uneaten food from their aquarium after a set period. For my tank, I use a 30-minute window.

I add the Fluval Bug Bites to the tank and set a timer for 30 minutes to remind me to remove any uneaten food. This allows my tetras to have their share and gives my Corydoras time to find the Bug Bites as well.

When I first started this feeding method, there was usually a significant amount of food left to be removed. Each time, I reduced the amount of Bug Bites I added to the tank.

Now, there is rarely any food left over at the end of the 30-minute window, helping to keep my tank water clean and reducing the frequency of water changes required.

Do They Sink?

Fluval Bug Bites do sink and can pass through the water column quickly, making it challenging for some mid-level feeding fish to catch them.

In the video clip above, I intentionally held the Bug Bites under the water surface to demonstrate how quickly they can move through the water column.

If you drop the Bug Bites onto the surface of your tank water, they will float for a while before sinking.

Using the pepper grinder method mentioned earlier in the article to crush the granules usually slows their descent through the water column.

This slower pace makes it much easier for mid-level feeders like tetras and rasboras to enjoy the food.

Final Thoughts

Fluval Bug Bites are a great choice for fish enthusiasts seeking a nutritious everyday feeding solution for their insectivore fish.

While they may present some challenges with micro fish, the range of granule sizes and formulas cater to various fish species.

The high protein content and micronutrient profile make Bug Bites an excellent choice for popular tropical fish and can help enhance their overall health and well-being.

If you’re looking for a premium fish food that your aquatic friends will love, Fluval Bug Bites should certainly be on your list of options to consider.
