Tropical fish flakes
Tropical fish flakes are the standard everyday food for most community tropical tanks — a dried, floating flake formulated to cover the general nutritional needs of a mixed group of small tropical fish. Our range includes flake foods such as Supa Tropical Flake Food and King British Tropical Flake, both built as a general-purpose staple rather than for one specific species.
What's actually in a tropical flake food
A general tropical flake is formulated to suit a range of common community fish at once, balancing protein, plant matter and vitamins into a single product rather than tailoring to one species' specific needs. This is exactly why it works well as the everyday staple in a typical mixed tank of tetras, guppies, mollies and similar small tropical fish.
Flakes float initially and then gradually break apart and sink, which suits fish that feed at different levels of the tank over the course of a meal, rather than only those that feed right at the surface.
How much to feed, and the overfeeding trap
The single most common mistake with flake food is feeding too much. A pinch that disappears within two to three minutes is generally the right amount for most small community tanks — anything left floating or sinking uneaten after that is excess that will foul the water rather than being eaten later.
Feed once or twice a day rather than leaving food available constantly, and consider skipping a day occasionally, which mirrors how fish would naturally go without food some days and helps prevent the water-quality problems that overfeeding causes.
Storing flake food properly
Keep the tub sealed and away from damp, and use it within the timeframe suggested on the packaging once opened — flake food that has gone soft, stale or damp loses nutritional value and is more likely to cloud the water when fed. Buying a size you will get through in a reasonable time beats a large tub that sits half-used for months.
If you keep fish with more specific dietary needs alongside your general community fish, a flake food is a good base to build from, with the odd supplementary feed of something more targeted rather than relying on flakes alone for a specialist species.

Common questions
- How often should I feed tropical fish flakes?
- Once or twice a day is standard for most community tanks, feeding only what your fish can eat within two to three minutes. Skipping a day occasionally does no harm and can help prevent overfeeding-related water quality problems.
- Why is my tank water cloudy after feeding flakes?
- This is almost always overfeeding — uneaten flake breaking down in the water clouds it and can affect water quality over time. Reduce the amount you feed and remove any obvious uneaten food after a few minutes rather than leaving it to decompose.
- Can I feed flake food to all my tropical fish?
- A general tropical flake suits most common community species, but fish with more specialised diets, such as strict bottom feeders or specific herbivores, often do better with a food formulated for their needs alongside or instead of a general flake.
- Do flakes lose their nutritional value over time?
- Yes, once opened, flake food gradually loses some nutritional value, particularly if exposed to damp or air over an extended period. Buy a size that will be used within a reasonable time and keep the tub sealed between feeds.
