Amazon Zebra Shrimp - Euryrhynchus amazoniensis : Complete Shrimp Profile & Care Guide
Table of contents
Introduction
The Amazon Zebra Shrimp (Euryrhynchus amazoniensis) is a fascinating and visually striking freshwater shrimp species. Unfortunately, these Shrimp are rarely imported and are not easy to obtain in the trade. The resilient and docile nature of this invertebrate is just one of the reasons why Dwarf Shrimp are a popular species for aquarium enthusiasts. While they share similar requirements to other Dwarf Shrimp, Amazon Zebra Shrimp tend to fare best in slightly acidic, softer water.
Fortunately, with proper care, these shrimp are relatively easy to maintain and can thrive in a well-maintained aquarium with plenty of hiding places and good water quality. Adding a layer of dried leaves to the aquarium floor can also be beneficial to the health and well-being of these fascinating creatures. With attention to these key elements, Amazon Zebra Shrimp can be a remarkable addition to any freshwater aquarium.
Amazon Zebra Shrimp should be kept in groups of at least six individuals to promote natural behaviour and reduce stress. It would be best to only house these Shrimp with more petite, peaceful fish such as Dwarf Barbs, Tetras or Pseudomugil Rainbowfish. Due to their small size, this Peruvian Shrimp should naturally not be kept with predatory fish, nor should you keep them with Crayfish or Crabs as it will result in death.
The Amazon Zebra Shrimp is characterised by its bold pattern of darker horizontal stripes on a light reddish-brown body extending to the caudal fin. Their body is also covered in dark spots. In addition, these Shrimp have hairy brownish-blue coloured claws that are not particularly powerful and are not dangerous to fish. There is also a light blue-coloured variant with dark blue horizontal stripes, although this is rarely seen.

Sexual Dimorphism
When it comes to the Amazon Zebra Shrimp, the difference between the male and female is a classic example of sexual dimorphism in small aquarium shrimp. Interestingly, the females tend to be noticeably larger than the males, but the males sport the larger claws. This fascinating aspect of the Amazon Zebra Shrimp's biology is just one of many things that makes this species such an intriguing subject for aquarium enthusiasts and biologists alike.

Natural Habitat
The Amazon Zebra Shrimp are primarily found in the Rio Nanay in Peru in South America; however, you can also find them in Bolivia, Venezuela and the Amazonas state in Brazil. These Shrimp inhabit shallow, moderate-flowing, warm waters typically associated with driftwood and aquatic vegetation and often in large groups.
Breeding
When it comes to breeding Amazon Zebra Shrimp in a home aquarium, proper water conditions are key. With optimal conditions, these shrimp are likely to produce regularly, providing a fascinating glimpse into the intricacies of their reproductive process.
Female Shrimp who are ready to be fertilised will develop a saddle shape that appears more prominent, and eggs will be visible underneath their abdomen. It's not uncommon to see female Shrimp tumbling their eggs underneath, a behaviour that adds another layer of interest to observing these creatures in their natural habitat.
What's particularly fascinating about the Amazon Zebra Shrimp is that, unlike some other species, the babies do not go through a larval stage. Instead, they are born as mini replicas of adult Shrimp, an adorable sight to see. First, however, it's important to take measures to protect these tiny creatures from the suction of power filters. By covering intakes with fine sponges or gauze, we can prevent unnecessary deaths and ensure the safety of the new offspring.
Even from birth, these shrimplets have a voracious appetite and will consume the same foods as the adults. Witnessing their growth and development from birth is a fantastic experience that highlights just how remarkable these creatures truly are.
Diet & Feeding
Like many other freshwater Shrimp, Amazon Zebra Shrimp are opportunistic feeders, consuming various food sources. They are primarily herbivorous, grazing on surfaces of rocks and plants to feed on algae and biofilm. However, they also consume detritus and small invertebrates when available.
One of the most interesting aspects of their feeding habits is their ability to act as cleaning agents in the aquarium, removing dead tissue and parasites from fish and other aquatic organisms. In the home aquarium, these Shrimp will readily accept commercial foods such as shrimp pellets, algae wafers, and blanched vegetables.
However, ensuring that Amazon Zebra Shrimp are fed a balanced and varied diet is essential to their overall health and well-being. By maintaining good feeding habits and water quality, we can help these amazing creatures thrive in captivity.
