For cichlids that feed on plants, such as Tropheus, this food contains a high proportion of plant-based ingredients. With nutrient-rich algae such as spirulina, chlorella, nannochloropsis and kelp, plus red coral algae rich in minerals and trace elements, fish can enjoy a species-appropriate diet containing fibre and grains such as they would eat in nature. In nature, herbivores always consume a certain proportion of animal-based substances (e.g. small organisms living in plants), so this food also includes some components of this type.
