TetraMin Granules, 15 g is a granular staple food for all ornamental fish from the German brand Tetra. The small granules soften quickly in water and sink slowly, so fish feeding at the surface, in mid-water and near the bottom all get some. According to the manufacturer, it contains protein, vitamins, lecithin and a colour-enhancing additive, while the BioActive formula supports long, healthy lives. The 15 g pack is handy for trying it out.
Granules or flakes
Flakes are a classic food, but they stay near the surface longer, so fish in the middle and lower levels may get less. Granules sink slowly, spreading food through the water column. They also crumble less and cloud the water less. Many fishkeepers alternate flakes and granules for a more varied diet. More in aquarium fish food: how to feed.

How to feed
Feed fish once or twice a day, in portions they finish within a few minutes. Remove leftovers, as uneaten granules decompose and spoil the water. A weekly fasting day is good for digestion and tank cleanliness. Granules suit adult fish as a staple; fry do better on a dedicated food such as TetraMin Baby.
Adding variety
Alternate granules with flakes such as TetraMin flakes, and occasionally use colour foods like TetraRubin. Goldfish, cichlids and discus have their own specialised foods tailored to their needs.
Water clarity
Overfeeding is the main cause of cloudy water and fish disease. If the water does go cloudy, check the filter, do a partial water change and cut portions. Water conditioners such as Rikka Clear Water help maintain balance. On basic equipment, see aquariums for beginners: what to buy.
Storage
Keep the pack tightly closed somewhere cool and dry. Once opened, use within 2–3 months before the vitamins degrade.
Who it suits
