Pros
- Black soldier fly larvae first — bettas are insectivores, so this suits them well
- Slow-sinking micro granules a betta grabs one at a time, so counting portions is simple
- Small batches and a resealable bottle keep it fresh for a single small fish
- Good colour support without relying on artificial dyes
Cons
- A little pack lasts one betta a long time, so watch the date and keep it dry
- Some fussy bettas take a few days to switch from their old pellet
The right diet for an insectivore
In the wild a betta hunts insects and larvae at the surface, so a food built on black soldier fly larvae matches its natural diet far better than a grain-based pellet. The slow-sinking micro granules hang near the top long enough for a betta to pick them off one by one — which is exactly what makes portioning so easy. You are not guessing at a pinch; you are counting out pellets.
Bettas are easy to overfeed
A betta’s stomach is tiny — about the size of its eye — and bettas will happily beg for more than they need. Stick to a few granules once or twice a day, and a weekly fasting day does no harm at all. Overfeeding is the usual cause of bloating and constipation in bettas, and the uneaten food quickly fouls what is often a small tank.
How it fits with our other picks
If you keep a mixed community as well as a betta, the Fluval Bug Bites Tropical Flakes cover the other fish with the same insect-based recipe. For the full range and the two-minute feeding rule, see our fish food hub.

Fluval Bug Bites Betta — frequently asked questions
How many granules should I feed a betta?
A betta's stomach is roughly the size of its eye, so only a few granules once or twice a day. A common routine is two or three pellets, twice daily — and it is fine to skip a day each week. Whatever they don't eat in two minutes was too much.
Can a betta live on this alone?
It works as a staple, but variety is better. Rotate in the occasional frozen or freeze-dried bloodworm or brine shrimp as a treat. A little variety improves colour and interest without overfeeding.
My betta is bloated — am I overfeeding?
Very likely. Bettas are prone to bloating and constipation from overfeeding, and the leftover food also fouls a small tank fast. Cut back the portion, feed a fasting day, and do a water change.
