Sera Crab Loops 100ml

Sera Crab Loops 100ml

Sera Crab Loops 100ml is a sinking, water-stable staple food for all crabs kept in freshwater and marine aquariums. It is formulated to provide the nutrients crabs need for healthy growth, natural colouration and safe moulting. It suits South African hobbyists keeping freshwater crabs, mangrove crabs or crayfish who want a natural diet free of artificial dyes and preservatives.

Sera developed these loops around how crabs and crayfish actually feed in the wild. Each loop holds its shape for a very long time, so your crustaceans can grab a piece, carry it off and eat it slowly in a hiding place without polluting the water. The recipe combines plant and animal ingredients, including spirulina and willow bark, and contains a measured amount of calcium to support the moulting process. Sera describes it as a complete feed for all crustaceans.

Key Benefits

• Complete staple diet: the balanced, close-to-nature composition is designed to meet the full nutritional requirements of crabs.
• Supports safe moulting: contains an appropriate amount of calcium (1.8% Ca) to help crabs and crayfish through each moult.
• Healthy growth and natural colour: spirulina, Haematococcus algae, paprika and carrots are included in a recipe aimed at growth and vivid natural colouration.
• Fertility and resilience: the formula is designed to support fertility, splendid colouration and disease resistance.
• Water-stable sinking loops: the loops sink to the substrate and keep their shape for a long time, so they don't cloud or foul the water.
• Matches natural behaviour: the loop shape is easy for crustaceans to grab, carry away and eat slowly in a hiding place, just as they would in the wild.
• Plant and animal ingredients: fish meal, gammarus meal and green-lipped mussel meat meal sit alongside spirulina, stinging nettle, alder cones and willow bark.
• No dyes or preservatives: like all Sera aquarium foods, Crab Loops belongs to the Sera "Nature" range and contains no artificial colourants or preservatives.
• Prebiotic support: contains mannan oligosaccharides (0.4%).

How to Use

• Drop the loops into the aquarium, where they will sink to the bottom.
• Let your crabs or crayfish find them, pick them up and carry them off to eat at their own pace. This is normal, natural feeding behaviour.
• Because the loops are water stable, they can be eaten slowly over time without breaking down and polluting the tank.

Dosage

• Feed sparingly once daily.

Suitable For

• All crabs in freshwater and marine aquariums, including mangrove crabs.
• Crayfish species such as Astacus, Cherax and Procambarus.
• Sera labels the food as a complete feed for all crustaceans.

In nature, most crayfish and many crabs, such as mangrove crabs, feed mainly on fallen leaves and other organic material, including carrion. Aquatic animals such as insect larvae, gammarus and aquatic snails are also a regular part of their diet. That is why Sera Crab Loops contains high-quality ingredients of both plant and animal origin.

Shrimps of the genera Caridina and Neocaridina mostly graze on periphyton growing on leaves, roots and stones. For these, Sera offers a separate shrimp food that softens over several hours so the shrimps can graze it slowly, matching their natural feeding habits. Sera's crab food was developed specifically for the needs of crabs. Both foods contain an appropriate amount of calcium to support safe moulting.

Frequently Asked Questions

Can I use Sera Crab Loops in a marine aquarium?
Yes. Sera formulated Crab Loops as a staple food for all crabs in both freshwater and marine water, so it suits mangrove crab setups as well as freshwater crab and crayfish tanks.

How often should I feed my crabs or crayfish?
Feed sparingly once daily. Because the loops stay intact for a long time, your crustaceans can carry them away and eat them slowly without the food breaking down and polluting the water.

Why do my crabs carry the loops away instead of eating them straight away?
This is natural behaviour. In the wild, crabs and crayfish often take food to a hiding place to eat it. The loops are shaped to be easy to grab and transport, so carrying them off is exactly how the food is meant to be used.

Does this food help with moulting?
It contains calcium carbonate and Ca-caseinate, giving a calcium content of 1.8%. This appropriate calcium level is included to support a safe moulting process.

Is it suitable for Cherax crayfish, which are popular in South Africa?
Yes. Sera lists crayfish species such as Cherax, Astacus and Procambarus among the animals this crab food was developed for. Their natural diet of leaf litter, organic matter and small aquatic animals is reflected in the mix of plant and animal ingredients.

Does Sera Crab Loops contain artificial colours or preservatives?
No. It is part of the Sera "Nature" range, which uses no dyes or preservatives. Natural colouration is supported by ingredients such as spirulina, Haematococcus algae, paprika and carrots instead.
