Tetra covers the everyday feeding of a freshwater tank. The tropical staples are TetraMin Tropical Flakes and Grans, TetraColour Tropical Flake for colour development and TetraPro Tropical Crisps; the coldwater side is Tetra Goldfish Flakes, Goldfish Grans and TetraPro Goldfish Crisps. TetraPro Pleco Wafers feed plecos and other grazing algae eaters, Fun Tips tablets stick to the glass, and the FreshDelica sachets — bloodworms, brine shrimps and krill — are gel foods meant as an addition to the staple diet rather than a replacement for it. Tetra Pond Sticks are the one pond product here, for goldfish and koi.
Match the food to where your fish actually feed. Flakes float, granules sink slowly, and wafers go straight to the bottom, so a tank of surface feeders and a bristlenose need different things. FreshDelica is worth knowing about if you have been buying frozen: it keeps without a freezer and carries no risk of introducing parasites. The Weekend and Holiday gel blocks are for time away, not everyday feeding. Follow the feeding directions on the pack — overfeeding, not the food itself, is what fouls the water.
