Brine Shrimp
Brine shrimp are a highly popular live feed across marine and freshwater aquaculture, widely used as a staple for developing fish. They typically contain 50–60% protein and 15–20% lipids, providing excellent nutrition and stimulating natural hunting behaviour.
However, adult Artemia lack significant levels of essential fatty acids like EPA and DHA, which are vital for optimal fish health, coloration, and development. Supplementing adult brine shrimp with a high-protein dry feed or HUFA-enriched diet is recommended to create a balanced feeding regimen.
Their darting motion encourages active feeding, making them ideal for promoting natural hunting instincts in marine species.
Dosage instructions
Gamma live can be placed directly into the aquarium, but we recommend straining off the water before putting in the aquarium. This aids nutrient control.
Use as frequently as required, ensuring full consumption and no wastage.
Brine Nauplii
Brine shrimp nauplii are among the first live foods used in aquaculture, ideal for larval and juvenile fish. They are smaller, more digestible, and contain higher levels of essential fatty acids than adult Artemia, offering a superior nutritional profile during early development.
Typically containing 50–60% protein and 15–20% lipids, nauplii provide readily available energy and nutrients critical for rapid growth and survival. Their constant swimming movement triggers a strong feeding response, supporting natural predatory behaviour in both marine and freshwater fry. For best results, they can be used as a primary starter food before transitioning to adult Artemia or formulated feeds.

Marine Copepod
Marine copepods form the foundation of most marine food webs and are widely regarded as the gold standard live feed for marine fish larvae. Containing 45–50% protein and high levels of essential fatty acids (EPA and DHA), they naturally deliver balanced nutrition that supports brain, eye, and immune system development.
Copepods also supply micronutrients such as iodine, carotenoids, and vitamins that enhance growth and coloration. Their natural swimming behaviour stimulates feeding, and their small prey size makes them ideal for delicate or high-value marine larvae like sea bass, sea bream, groupers, and snappers. They also contain digestive enzymes that aid early-stage digestion when larval fish are still developing their own.

Phytoplankton Blend
Phytoplankton are the base of marine ecosystems, providing essential nutrients to corals, larvae, and zooplankton. They typically contain 20–40% protein, 10–25% lipids, and valuable omega-3 fatty acids like EPA and DHA, supporting tissue growth, coloration, and immune function. Species such as Isochrysis, Nannochloropsis, and Tetraselmis are especially rich in HUFAs and pigments, helping drive coral health and vibrant colour. Phytoplankton also contribute vitamins, amino acids, and trace minerals (e.g., nitrogen, phosphorus), which sustain coral metabolism and skeletal development. Regular dosing maintains reef stability and fuels zooplankton growth, indirectly supporting fish and invertebrates.
Dosage instructions
Heaviest dose: 10 ml per 100 L. Start at ½ dose and build over 2–3 weeks. Shake well before use
Dose programme: Week 1: 1 ml/100 L/day → Week 2: 2 ml/day → Week 3: 3 ml/day → Week 4: 4 ml/day (baseline).
From week 4, increase by 1 ml weekly until desired zooplankton production.
Daphnia
Daphnia, or water fleas, offer 45–50% protein and 6–10% fat, making them a nutritious feed for small and juvenile freshwater fish. Their erratic swimming motion triggers strong feeding responses and encourages growth and coloration. They also provide essential minerals and amino acids but may require enrichment to improve HUFA content for marine or high-HUFA-demanding species. Daphnia are particularly suitable for freshwater and brackish fish, like tetras, rasboras, gouramis, and juvenile mullet, offering a balanced, digestible diet.

Mysis Shrimp
Mysis shrimp provide a rich diet with 60–70% protein and 8–10% fat, including abundant EPA and DHA. They are ideal for medium to large marine carnivores, offering a nutrient-dense, meaty diet with excellent digestibility and active prey movement. Their nutritional density surpasses that of brine shrimp, making them suitable for species such as seahorses, pipefish, mandarins, anthias, wrasses, and dwarf angelfish. Mysis support energy, growth, and vivid coloration in both aquaculture and advanced marine aquarium systems.

River Shrimp
River shrimp are a high-protein (40–50%), mineral-rich feed ideal for larger freshwater, brackish, and some marine fish. They contain around 5% fat with significant levels of calcium and phosphorus, promoting strong bone and scale development. Their active swimming behaviour stimulates natural hunting instincts and encourages feeding in predatory species like catfish, cichlids, and large cyprinids. Though rich in energy, they benefit from omega-3 enrichment for species requiring high HUFA intake.

Bloodworm
Bloodworms (Chironomid larvae) are a 40–50% protein, 2–4% fat, and 20–25% carbohydrate live or frozen feed suitable for freshwater and some marine species. Their red pigmentation (from haemoglobin and iron) enhances fish coloration and stimulates feeding. Bloodworms are highly palatable, making them ideal for bettas, tetras, barbs, gouramis, dwarf cichlids, and catfish, especially during conditioning or breeding. As they are low in HUFAs, they are best used alongside other live foods for a complete diet.
