Dietary Requirements and Feeding Habits

Macrobrachium Australiense, being omnivorous freshwater shrimp, eat a wide range of foods. In their natural home, they enjoy plants, small animals, and even decaying matter. Knowing what they like to eat is key to keeping them healthy in an aquarium.

Natural Diet Preferences

In the wild, these shrimp eat both plants and animals. Their diet includes:

• Aquatic plants and algae
• Small invertebrates like insect larvae, crustaceans, and mollusks
