Contents: available in 50 ml and 100 ml — fresh in stock, ready to use.

✅ Level: Easy — Main and colour food for bottom-dwelling fish. No special equipment needed.

Sera Plankton Tabs Nature is the colour food for all bottom-dwelling fish (such as catfish and roach) and invertebrates, in both fresh and saltwater. Zooplankton (7% krill) and phytoplankton (24% spirulina) naturally promote colour development, without artificial colourings or preservatives. The highly digestible food also supports healthy growth, a strong immune system, and fertility. The tabs sink to the bottom, retain their shape for a long time, and do not pollute the water.
