TetraMin, 100 ml is a staple flake food from the German brand Tetra for complete everyday nutrition of ornamental fish. It's a carefully chosen blend of highly nutritious ingredients, vitamins, minerals and trace elements. The tub contains seven different flake types made from more than 40 raw materials. The flakes float and sink slowly, so the food reaches fish feeding at the surface and in mid-water. The BioActive formula and prebiotics support fish health and nutrient absorption.
How the food works
Flakes are the most versatile food format. They crumble easily between your fingers, so they suit both large and small fish, and the different flake types in one tub add variety. Slow sinking gives fish at different levels time to feed. The prebiotic — oligofructose (1%) — improves digestion, and well-digested food produces less waste, which, according to the manufacturer, helps keep the water clear.

How to feed
The general rule for flakes is to give as much as the fish eat in 2–3 minutes, 1–3 times a day. Remove any leftovers that sink to the bottom, as they spoil the water. Give large fish whole flakes and crumble them for small fish. You can have a fasting day once a week. Overfeeding is the most common beginner mistake: uneaten food rots, raises ammonia and makes the water cloudy. Keep the tub closed and dry, and don't store it above the tank.
How to round out the diet
TetraMin works as a staple food, but for variety alternate it with granules, chips or frozen foods. Add sinking tablets for bottom feeders and a spirulina food for herbivores. Large cichlids and discus are better off with specialised foods such as Tetra Discus.

Who it suits
Most tropical ornamental fish — guppies, mollies, tetras, barbs, danios and gouramis — and beginners looking for a reliable staple food. More foods are in the fish food section.
Verdict
TetraMin is a proven, versatile flake food: seven flake types, 46% protein, prebiotics and BioActive for everyday feeding of most fish. A good dietary base. The downsides are that bottom feeders need a separate food and the recipe includes colourants.
