What is Moina Macrocopa?

Moina Macrocopa, commonly known as water fleas, are small freshwater crustaceans belonging to the order Cladocera. They are part of the larger family of Daphniidae, but Moina are distinct from the more commonly known Daphnia. Here are some key details about Moina Macrocopa:

Physical Characteristics:

  • Size: Moina Macrocopa are small, typically ranging from 0.3 to 1.0 mm in length, making them slightly smaller than their Daphnia relatives.
  • Body Structure: They have a transparent, oval-shaped body with a single large compound eye. Their body is covered by a shell called a carapace, and they have a pair of antennae used for swimming.
  • Reproduction: Moina can reproduce both sexually and asexually. Under favorable conditions, they reproduce asexually through parthenogenesis, which allows for rapid population growth.


  • Environment: Moina Macrocopa are found in a variety of freshwater environments, including ponds, lakes, and slow-moving rivers. They thrive in nutrient-rich waters and can tolerate a wide range of temperatures and water conditions.
  • Adaptability: They are highly adaptable and can survive in environments with low oxygen levels, making them hardy and easy to cultivate in aquariums.


  • Feeding Habits: Moina are filter feeders, consuming bacteria, algae, and other small organic particles suspended in the water. This diet makes them an important part of the aquatic food web, as they help control algae levels and recycle nutrients.

Key Features:

  • High-Quality Live Feed: Moina Macrocopa are known for their excellent nutritional value, making them a superior choice for feeding fry, small fish, and other aquatic pets.
  • Rich in Protein: These water fleas are an exceptional source of protein, promoting healthy growth and vibrant coloration in your aquatic life.
  • Easy to Cultivate: Our culture comes with simple instructions, making it easy to maintain and cultivate your own live feed supply at home. 
  • Chemical-Free: Grown in a controlled environment, our Moina Macrocopa culture is free from harmful chemicals and pathogens, ensuring the safety of your fish and aquatic pets.
  • Natural Behavior Stimulation: Watching your fish hunt and consume live prey encourages natural feeding behaviors, providing both mental and physical stimulation.

  • Reproduction Rate: Moina reproduce faster than Daphnia, providing a more consistent and abundant food source for your aquarium.
  • Nutritional Value: Both Moina and Daphnia are highly nutritious, but Moina are particularly rich in protein and fats, which are essential for the rapid growth and development of young fish.
  • Ease of Cultivation: Moina Macrocopa are easier to culture in a wider range of conditions compared to Daphnia, which often require more specific water parameters and care.
  • Environmental Tolerance: Moina can thrive in a variety of water conditions and are more resilient to changes in water quality, while Daphnia are more sensitive and may require more careful monitoring.
