How to Differentiate Amano Shrimp from Macrobachium Shrimp
Overview of Amano and Macrobachium Shrimp
Amano shrimp (Caridina multidentata) are a species of freshwater shrimp native to Japan and Southeast Asia. They are popular in the aquarium trade and are often used as algae eaters. Macrobachium shrimp (Macrobrachium sp.) are also a species of freshwater shrimp found in the same regions. They are often mistaken for Amano shrimp due to their similar appearance, but the two species have distinct physical characteristics that will help you differentiate them.
Differences in Appearance
The most noticeable difference between Amano and Macrobachium shrimp is their size. Amano shrimp are usually smaller than Macrobachium shrimp, with a maximum size of about two inches in length. Macrobachium shrimp can grow up to four inches in length. Additionally, Amano shrimp have a slightly transparent body, while Macrobachium shrimp are more opaque.
Differences in Behavior
Amano shrimp are generally more active and energetic than Macrobachium shrimp, and they are better at controlling algae in the aquarium. Amano shrimp are also more social, often living in groups. Macrobachium shrimp, on the other hand, are more solitary and tend to spend most of their time hiding in crevices of rocks or driftwood.
Differences in Diet
Amano and Macrobachium shrimp have different diets. Amano shrimp are omnivores, meaning they feed on both plant and animal matter. They are scavengers and will eat algae, detritus, and various types of food specifically designed for shrimp. Macrobachium shrimp, on the other hand, are mainly carnivorous, feeding mostly on insect larvae, worms, and small crustaceans.
Conclusion
Amano shrimp and Macrobachium shrimp are two species of freshwater shrimp native to Japan and Southeast Asia. While they may look similar, these two species have distinct physical characteristics and behaviors that can help you differentiate them. Amano shrimp are usually smaller, more transparent, and more active than Macrobachium shrimp, and their diets are also different. If you know what to look for, it should be easy to tell the difference between these two species.
