Description
Sera Spirulina Tabs
Sera Spirulina Tabs are a premium herbal food designed for ornamental fish and invertebrates that feed at the bottom of the aquarium. These sinking, attachable tablets provide a balanced, plant-based diet that supports healthy digestion, natural behaviour and long-term vitality.
As part of the Sera Nature range, Spirulina Tabs are produced without dyes or preservatives and reflect nutrition close to nature for mainly herbivorous aquatic species.
Herbal food for bottom-feeding ornamental fish
Spirulina Tabs are ideally suited for mainly herbivorous fish and invertebrates in both freshwater and marine aquariums. The tablets sink to the bottom or can be attached to the aquarium glass, making them perfect for species that prefer to graze.
With 25% spirulina for healthy digestion
The formula contains a particularly high proportion of 25% spirulina algae. Spirulina is rich in natural fibres, pigments and bioactive compounds that support healthy digestion, energy levels and liveliness.
Balanced nutrition for healthy development
The carefully balanced herbal composition supports steady growth, splendid appearance and species-appropriate behaviour. Natural plant ingredients supply essential nutrients without overloading the digestive system.
Attachable tablets for natural feeding behaviour
The gently manufactured tablets can be pressed onto the aquarium glass with slight finger pressure. This allows fish to graze naturally and enables fascinating observation, even of shy or nocturnal species.
Nutrition close to nature for herbivorous fish
Sera herbal foods are developed specifically for ornamental fish whose digestive tract and physiology are adapted to a mainly plant-based diet. Ingredients such as algae, herbs and vegetables provide fibre, secondary plant substances, pigments, trace elements and vital nutrients.
Sera offers herbal foods in multiple formats to match natural feeding habits, including flakes for surface feeders, granules for mid-water feeders and tablets for bottom feeders.
Clean feeding without water pollution
The tablets retain their shape while being grazed and do not cloud the water. This supports stable aquarium conditions and reduces maintenance requirements.
