Fish Science Betta Granules 35g | Insect-Based Betta Fish Food

FS Betta Granules are a specialist food designed specifically for Siamese fighting fish (Betta splendens), formulated to closely reflect the insect-rich diet bettas consume in their natural habitat. Presented as floating 0.5mm granules, they are sized and positioned to suit the feeding behaviour of bettas at the water surface.

Insect-Based Formula

Insect meal forms the foundation of this food, providing a protein source that mirrors what bettas naturally feed on. This makes the diet biologically appropriate and supports healthy digestion compared to formulas built primarily around fish or plant protein.

Natural Colour Enhancers

Rather than relying on synthetic additives, the granules include naturally derived colour-enhancing ingredients: spirulina algae, paprika, carrot, and shrimp. These support vibrant colouration in a way that works with the fish's own physiology.

Floating 0.5mm Granules

The granules are produced at 0.5mm — small enough for bettas to take comfortably — and are designed to float, encouraging natural surface feeding behaviour and making it easy to monitor how much your fish is consuming.

Sustainable Sourcing

The use of insect meal as a primary protein source reflects a more environmentally considered approach to fish food production, with a lower resource footprint than many conventional aquatic food ingredients.

A focused, biologically appropriate food for betta keepers who want to feed their fish in a way that supports health, colour, and natural behaviour.
