Xtreme So-Fly Black Soldier Fly Larvae Crumble 5 oz
Xtreme So-Fly Crumble is a slow-sinking insect-based fish food formulated with black soldier fly larvae as the first ingredient. Its irregular 0.5–1.0 mm crumble size is designed for small-to-medium freshwater fish that naturally feed on insects, larvae, and other small foods in the water column.
The formula combines black soldier fly larvae with fish meal, shrimp meal, fish protein concentrate, plant proteins, grains, vitamins, and trace minerals. This provides a balanced food with 37% crude protein and 8% crude fat for everyday feeding or dietary variety.
The 5 oz package is a practical size for community aquariums, fish rooms, breeders, and customers maintaining several tanks.

Why Use Black Soldier Fly Larvae?
Many freshwater fish naturally consume insects, larvae, and other small invertebrates. Black soldier fly larvae provide a highly palatable insect-based ingredient that can add variety to a feeding program built around quality commercial foods.
So-Fly should not be treated as a substitute for species-appropriate feeding. Herbivorous fish, specialized grazers, fry, large predators, and bottom feeders may require additional foods with different ingredients, textures, or particle sizes.
Slow-Sinking Crumble Format
Unlike a uniform pellet, So-Fly Crumble contains small irregular pieces measuring approximately 0.5–1.0 mm. The pieces sink gradually through the water column, encouraging fish to chase and pick at food at different depths.
The varied crumble size may be especially useful in mixed community aquariums containing fish with slightly different mouth sizes.
Feeding Directions
Feed a small amount one to three times daily, offering only what the fish can consume within a few minutes.
Start with less than you think is needed. Additional food can always be added, but uneaten food should be removed to help limit waste and declining water quality.
Adjust feeding according to:
- Number and size of fish
- Species and activity level
- Water temperature
- Breeding or growth stage
- Other foods offered
- Aquarium filtration and maintenance
Can It Be Used as a Staple Food?
So-Fly Crumble may be used as a regular food for suitable freshwater community fish. However, many aquariums benefit from dietary variety.
Rotate it with other appropriate foods such as:
- Krill- or shrimp-based pellets
- Spirulina foods for herbivorous and omnivorous fish
- Frozen foods
- Species-specific sinking foods
- Foods formulated for fry, shrimp, plecos, or large fish when needed
No single food is ideal for every species in every aquarium.
Does So-Fly Enhance Color?
A balanced diet may help fish maintain their natural coloration, but So-Fly should not be presented as guaranteeing brighter colors.
Color is also influenced by genetics, age, stress, water quality, lighting, social condition, and the rest of the diet.
Does It Improve Immunity?
So-Fly provides protein, vitamins, minerals, and a balanced amino-acid profile that support normal nutrition. It is not a medication or disease-prevention product and should not be described as directly boosting immunity or preventing illness.
Fish health also depends on stable water parameters, suitable temperature, compatible tank mates, appropriate stocking, quarantine, and regular maintenance.
Will It Produce Less Waste?
Appropriate feeding may help reduce uneaten food compared with using oversized or poorly accepted foods. However, no fish food can guarantee cleaner water.
Aquarium waste depends on:
- How much food is offered
- How completely it is consumed
- Fish metabolism
- Stocking level
- Filter maintenance
- Water-change schedule
Overfeeding any food can increase ammonia, nitrate, phosphate, algae, and organic waste.
Use with Bettas
The crumble size may be suitable for many bettas, although individual fish may prefer larger floating pellets or foods that remain near the surface longer.
Feed only a few appropriately sized pieces at a time and avoid allowing excess crumble to settle uneaten.
Use with Small Cichlids
So-Fly Crumble may be offered to small or juvenile omnivorous and insect-eating cichlids that can comfortably consume the particle size.
It may not be the best sole diet for specialized herbivorous African cichlids, large predatory cichlids, or adult fish requiring larger pellets.
Use in Community Aquariums
The slow-sinking, mixed-size crumble can help distribute food among surface, midwater, and lower-water-column feeders.
Watch the aquarium during feeding to confirm that shy or slower fish receive enough food and that aggressive feeders do not consume everything first.
Freshwater and Marine Use
Xtreme primarily presents So-Fly Crumble as a freshwater community fish food. Some marine fish may accept the crumble, but customers seeking a regular marine diet should consider a food specifically formulated and sized for marine species.
Avoid marketing the product as universally appropriate for all freshwater and saltwater fish.
Storage Instructions
- Keep the package tightly sealed
- Store in a cool, dry place
- Protect from moisture and direct sunlight
- Use clean, dry hands or feeding tools
- Do not return wet or contaminated food to the container
- Keep out of reach of children and pets
Important Feeding Note
Xtreme So-Fly Crumble is intended as food for ornamental aquarium fish. It does not replace proper filtration, water changes, testing, quarantine, or disease treatment.
Feed according to the needs of the fish and remove uneaten food. Overfeeding is one of the most common causes of cloudy water, algae growth, elevated nitrate, and poor aquarium conditions.
Frequently Asked Questions

What size are the crumbles?
The irregular slow-sinking crumbles are approximately 0.5–1.0 mm.
Is it a pellet?
No. It is a crushed or crumble-style food rather than a uniform round pellet.
What fish is it best for?
It is best suited to many small-to-medium freshwater community fish such as tetras, rasboras, barbs, danios, guppies, bettas, gouramis, rainbowfish, and small cichlids.
Can it be used as the main food?
It may be used regularly for suitable fish, although dietary variety is recommended when possible.
Is it slow sinking?
Yes. The crumble is designed to sink gradually through the water column.
How much protein does it contain?
The guaranteed analysis lists a minimum of 37% crude protein.
Does it contain added hormones?
Xtreme lists the formula as containing no added hormones.
Does it enhance fish color?
Good nutrition may support natural coloration, but results depend on the complete diet, genetics, water quality, lighting, and fish health.
Does it boost the immune system?
It provides nutrients that support normal health, but it is not a medication or guaranteed immune-system booster.
Will it keep the aquarium cleaner?
The small, palatable pieces may reduce uneaten food when fed correctly, but water quality still depends on portion control, filtration, stocking, and maintenance.
Can it be fed to bettas?
Yes, many bettas can eat the crumble, although some may prefer a larger floating food.
Can it be fed to fry?
The smallest pieces may be accepted by larger fry, but very small fry may require a finer powdered or specialized fry food.
Can it be used for saltwater fish?
Some marine fish may accept it, but it is primarily marketed for freshwater community fish. A dedicated marine formula may be more appropriate for routine marine feeding.
How often should it be fed?
Feed small portions one to three times daily, providing only what the fish can consume within a few minutes.
