Sera Spirulina Tabs

Sera Spirulina Tabs

Sera Spirulina Tabs are a sinking, plant-based tablet food for mainly herbivorous ornamental fish that feed on the bottom, and for invertebrates in both freshwater and marine aquariums. Each adhesive tablet contains 25% spirulina algae to support healthy digestion and liveliness. The tablets contain no dyes or preservatives, so they suit South African fishkeepers looking for a natural staple for bottom-dwelling grazers.

Key Benefits

• High spirulina content: spirulina algae makes up 25% of the recipe, an especially high share that supports healthy digestion and liveliness.
• Balanced composition: formulated to support healthy development, a splendid appearance and natural, appropriate behaviour.
• Sinks or sticks: the gently manufactured tablets sink to the substrate, or you can press them onto the aquarium glass with light finger pressure.
• Easier to watch your fish: fixing a tablet to the glass lets you watch your fish feed up close, including shy species that normally stay hidden.
• No dyes or preservatives: part of the sera "Nature" range, in which every aquarium food is made without dyes or preservatives.
• Complete feed: classified as a complete feed for all ornamental fish, so it can serve as a staple diet.
• Suits fresh and marine water: one food for herbivorous bottom feeders and invertebrates in both tropical community tanks and saltwater systems.

Nutrition Close to Nature

The sera herbal foods were developed for ornamental fish whose digestive tract and physiology are adapted to a mainly plant-based diet. A varied mix of herbal ingredients, including algae, herbs and vegetables, gives herbivorous fish the fibre they need, along with all the necessary nutrients and vital substances. These include secondary plant substances, pigments and trace elements, among many others.

The range also takes feeding habits into account, not just diet type. Sera offers herbal food in three forms:

• Flakes for ornamental fish that feed at the surface.
• Granules for ornamental fish that feed in the middle water layers.
• Tablets, such as Spirulina Tabs, for ornamental fish that feed on the bottom.

How to Use

• Drop the tablets into the aquarium so they sink to the bottom, where bottom-feeding fish and invertebrates can graze on them.
• To watch your fish feed, press a tablet gently against the inside of the aquarium glass with your finger until it sticks.
• Offer only as much food as your animals eat within a short time.
• Remove any uneaten food. Leftovers break down and can affect water quality, especially in warm South African summers.

Dosage

Feed once or twice daily, giving only as much as the animals take up within a short time.

Suitable For

• Mainly herbivorous ornamental fish that feed on the bottom.
• Invertebrates kept in freshwater and marine aquariums.
• Shy bottom dwellers that benefit from food placed where you can watch them eat.
• Freshwater and marine set-ups alike.
