Moina macrocopa

Quantity:  50+ml 

Quality: Tank bred under lab conditions.

Suitable for: Fry and small fish.

Nutritional values: A great source of protein, lipids, fibre, and carotenoids. Great for triggering predatory instinct as they are free swimming.

Difficulty level: Easy

Food: Chlorella culture, Spirulina powder, infusoria, soy- pea- wheat- and rice flour. Baker’s dry yeast (Yeast easily fouls the water and thereby making the culture crash. Flour water is less of a crash-prone food).

Reproduction rate: Extremely fast (mostly asexual by parthenogenesis, up to 20 eggs every 2 days).

Water parameters: Temperature 16°C to 30°C, pH 7-8,5. Use aged water; Tap water that you leave to off-gas chlorine for 24-48 hours before use. Frequent small water changes 10-20% every 2-3 days).

Air pump: Not needed. An air hose (no stone) with one bubble per second is good for circulation if your tank has a small surface area.

Lighting: Bright indirect sunlight or artificial light source for 8-12 hours daily, will boost algae growth for grazing.

Tank size: 5+L larger Is better. More surface area than depth.

Substrate: No need.

Size: 0,2-1mm

Colouration: Red, brown, grey and green tones, depending on oxygen levels and food sources.

Age expectancy: Up to 70 days.

Tip: Keeping snails (like Radix balthica, or Ramshorn snails) in a moina tank will aid to stabilize the eco-system and will help you against overfeeding. Combining moina and paramecium cultures can help a lot with keeping the culture stable. Moina cultures are prone to crashing; high density, over/under feeding, nitrate concentration and temperature shifts. We highly recommend always keeping more than one culture.
