Fluval Bug Bites Spirulina Flakes
A spirulina-first flake for herbivore-leaning fish that still need a complete diet. Fluval Bug Bites Spirulina Flakes lead with Hawaiian spirulina and add six vegetable ingredients alongside insect and marine proteins, across pack sizes from an 18 g trial pouch to a 180 g household size.
Key features
- Spirulina is the #1 ingredient – a plant-protein base suited to herbivorous and omnivorous grazers.
- 37% crude protein – moderate, balanced protein rather than a carnivore-level formula.
- Six vegetable ingredients – cauliflower, spinach, garlic, carrot, alfalfa meal and kelp for broad micronutrient coverage.
- Krill and shrimp meal included – marine protein and natural colour support alongside the plant base.
- No artificial fillers or preservatives.

Feeding directions
Feed as much as fish will clear in two minutes, two to three times daily. Remove uneaten flake to keep water quality up.
Suitable for, and not suitable for
Suitable for herbivorous and omnivorous freshwater and marine grazers – mollies, platies, plecos, tangs and similar species that benefit from a plant-forward diet. Not a good sole diet for strictly carnivorous fish, which need a higher protein formula than this one.
Goes well with
Fluval Bug Bites Algae Wafers for bottom-feeding grazers in the same tank, and a feeding clip for surface-grazing species like mollies and platies.
Warranty and delivery
Covered by the manufacturer's freshness guarantee in addition to your rights under Australian Consumer Law. Best used within 6 months of opening; store sealed in a cool, dry place.
Common questions
Is this suitable as a staple food, or just a supplement?
It's a complete flake food and can be fed as a staple for herbivore-leaning fish, not just an occasional green supplement.
Will this work for marine tangs?
Yes – the spirulina-forward, moderate-protein formula suits grazing marine herbivores as well as freshwater ones, though dedicated tangs may still benefit from additional dried seaweed or nori.
Is it reef or invertebrate safe?
It contains krill and shrimp meal along with a standard trace mineral inclusion of copper sulphate, as most commercial fish foods do – keep it away from copper-sensitive invertebrates if target-feeding rather than letting the whole tank graze.
Why is there no 90 g size?
This range is stocked here at 18 g, 45 g and 180 g; the 90 g size in Fluval's wider catalogue isn't part of this listing.
