Our full review
Fluval Bug Bites Fish Food brings a genuinely different protein source to the aquarium hobby, using black soldier fly larvae as the primary ingredient instead of the typical fish meal base found in most commercial diets. This insect-based formula taps into what many fish naturally forage for in the wild, making it a biologically appropriate choice for a wide range of tropical and freshwater species. The larvae provide a rich source of easily digestible protein along with essential fatty acids, and the recipe is rounded out with wholesome additions like salmon meal, shrimp, and a blend of vegetables and algae to create a balanced nutritional profile that supports healthy growth, energy, and immune function.
The pellets or granules are formulated to hold their shape well while also being easy for fish to break down, reducing waste and helping to maintain better water clarity compared to some lower-quality foods that cloud tanks or foul quickly. Fluval offers Bug Bites in multiple sizes and formats to suit different mouth sizes and feeding behaviors, from small granules ideal for tetras and other nano fish to larger pellets designed for cichlids and bigger community species. There are also specialized formulas within the line, including options tailored for bottom feeders and color-enhancing blends meant to bring out vibrant reds, oranges, and blues in ornamental fish.
Aquarists appreciate that this food doesn't rely on fillers or excessive plant-based binders, which means less bloating and more efficient nutrient uptake for the fish. The natural insect protein also tends to appeal strongly to picky eaters, often reigniting feeding interest in fish that have grown indifferent to older, less appetizing diets. Whether used as a staple food or rotated in alongside other options for dietary variety, Fluval Bug Bites has earned a solid reputation among hobbyists looking for a modern, sustainably sourced alternative that still delivers the nutritional density their aquarium inhabitants need to thrive.
What owners say
My cichlids love this!
Switched to Bug Bites a few months ago and my cichlids go crazy for it. Colors are noticeably brighter and less waste in the tank.
Great food, pellet size varies
Overall very happy with this food, my bettas eat it readily. Only issue is some pellets are a bit large for smaller fish.
Noticeable improvement in health
Been using this for my community tank for 3 months. Fish are more active and colors have improved significantly.
Goldfish approve
My goldfish took to this immediately. Water stays cleaner than with flake food. Just wish the bag resealed a bit better.
