Ninja Shrimp (Caridina serratirostris)

Are you looking to add some unique and colourful inhabitants to your aquarium? Look no further than the captivating Ninja Shrimp! These fascinating freshwater shrimp are known for their incredible ability to change colour rapidly, providing them with the ultimate camouflage to avoid predators in their natural habitat.

Despite their name, Ninja Shrimp are actually very peaceful and make a great addition to a peaceful community tank. While they can be a bit shy, they thrive in large groups and enjoy hiding amongst plants and driftwood.

When it comes to tank mates, it's vital to choose peaceful and tiny fish species to avoid any potential conflicts. Pygmy Corydoras and other micro fish are great options, but larger fish may see the shrimp as a tasty snack. You should also keep all types of crayfish and freshwater crabs away from Ninja shrimp, and small African Dwarf Frogs are also capable of catching the shrimp.

When setting up a tank for Ninja Shrimp, be sure to include plenty of hiding spots and foraging areas. Live plants like Java moss are a great addition, and shrimp tubes, rocks, and driftwood can mimic their natural habitat.

Ninja Shrimp come in many colour variations like yellow, orange, red, black, brown, cream, etc. There are many pattern variations as well; they can be with or without white stripes on the back or numerous small stripes across the body.

Overall, Ninja Shrimp are relatively low-maintenance and easy to care for, making them an excellent option for beginners and experienced aquarists alike. With their stunning colour variations and unique abilities, they are sure to add a touch of intrigue and excitement to any aquarium.

Ninja Shrimp are omnivores and consume a wide range of foods in their natural habitat, including algae, biofilm, detritus, and various types of plant matter. In an aquarium, they will readily accept a variety of foods, including algae wafers, shrimp pellets, and blanched vegetables like zucchini and spinach.

They are also known to enjoy live foods like brine shrimp, bloodworms, and daphnia. However, it's essential to ensure their diet is balanced and not too heavy in protein, as too much protein can lead to health issues.

Providing a diverse and balanced diet will not only keep these shrimp healthy but also enhance their vibrant colouration.

Sexual Dimorphism

Ninja Shrimp exhibits clear sexual dimorphism, which means that males and females have different physical characteristics. In this species, males tend to be smaller and slimmer than females, with a more pronounced and curved rostrum. Females, on the other hand, have rounder and larger bodies, with wider abdomens to accommodate eggs.

The most striking difference, however, is in their colouration. Males are usually more vibrant in colour, while females tend to be more subdued. The female's colouring is an adaptation to protect her and her developing eggs from predators by blending into her environment.
