This rare and exceptional shrimp is best known for its remarkable color-changing ability!

The Ninja Shrimp (Caridina serratirostris) is a somewhat uncommon and very colorful shrimp species that is fairly widespread across the Indo-Pacific, from Madagascar to many Pacific islands. This shrimp is most notable for its incredible color-changing ability when it is in good health. It can change to a wide variety of colors, particularly shades of red, orange, brown, and cream.

The Ninja Shrimp, like most shrimp, lives in large colonies and spends most of its time foraging for food. It is a voracious eater of algae in the aquarium and is not only a very active, outgoing species, but it is also very useful as a solution to fighting algae issues. It aggressively feeds on most varieties of algae and, in appropriate numbers, will often eradicate even the most persistent algae growth on plants and other aquarium decorations. It is also very effective in eating decaying plant matter, such as shed leaves and needles of aquarium plants. However, it does not bother or damage ornamental plants.

Care for the Ninja Shrimp is fairly simple and straightforward. They do not require the more acidic pH of their "bee-type" Caridina cantonensis cousins. However, unlike most other dwarf shrimp, they prefer relatively warm water. Their water requirements are otherwise very similar to Neocaridina shrimp.

The Ninja Shrimp is a low-form breeder that requires varying degrees of salinity for its fry to develop, but adult-form specimens thrive in freshwater. It is a scavenger and is very useful in planted and nano aquariums. The bulk of its diet is biofilm, algae, and decaying plant matter so it will work diligently to clean up detritus in any aquarium. It feeds constantly, so it displays constant activity. In a less mature aquarium, it should be fed high quality flake and mini pellet dry foods with high algae/spirulina/plant content. GlasGarten Bacter AE is also a superb food, as it will dramatically increase biofilm growth in the aquarium.

Our Spirulina flakes and BacterAE make excellent staple food products for these shrimp.
  • Warning! Avoid any food product, medication, or plant fertilizer that contains Copper of any form. Copper is toxic to invertebrates. Many commercial fish foods, medications, and plant fertilizers contain copper or more commonly copper sulfate. Always look at the ingredient list for any product going into the aquarium to ensure they are copper free.
