Caridina multidentata was one of the first freshwater shrimps was brought to aquarium over 20 years ago by Takashi Amano (from him comes the popular name). Very quickly it became a hit on aquarist market, mainly thanks to its big appetite for algae. As one of few goes well through water conditions changing in aquarium. Its tolerance to pH and hardness of water makes it very easy to keep shrimp. It shouldn't be kept in one tank with aggressive fishes. The best would be company of 4 - 5 cm fishes. It feels good in company of filtrating shrimps. If you want to keep it with shrimps from Macrobachium kind it will soon become their snack:) Markedly pigmentation comes when there are humid acids in water. Spots on body become red-brown, and the line becomes more visibly then.
