The natural flake food for smaller cold-water fish without dyes and preservatives. sera Goldy Nature is the natural staple for smaller goldfish (including fabulous variants) and other finicky coldwater fish that do not require dyes and preservatives. Thanks to insect flour from Hermetia flies, it contains a high-quality protein source, which is also resource-friendly. The balanced ratio of plant and animal ingredients ensures an easily digestible food that supports health and sumptuous colours. The flakes hold their shape, are suitable for cold water fish on the surface and do not cloud the water.
