The Amano Shrimp was introduced to aquarium society by Takashi Amano in 1994 with the book he wrote. He wrote about how effective is Caridina Japonica in controlling algae in the planted aquariums. After that Caridina Japonica became famous and many planted aquarium hobbyists started to keep this species in their tanks.

Amano shrimp has an extreme appetite to consume all kinds of algae in freshwater. They also consume other leftovers of plants, fish foods and other detritus. This is an incredible and invaluable benefit for planted tanks since they break up all unwanted materials into smaller and recyclable organic wastes.

Amano Shrimp can tolerate salinity at low levels. Their fry requires saline water for growing (the fry only). The average life span of Amano Shrimp is around 2-3 years.

Amano shrimp is a non-aggressive shrimp that is proper for the community tanks without any predators. When there is no predator, they are very active and good at cleaning aquariums from algae and other wastes.

Water Parameters:

Temperature: 15-29°C
pH: 6,0 – 8,0
Hardness: 5-15 dGH

They can be kept well between pH 6,5-7,5 and hardness value around 7-9 but they can survive under a wide range of water conditions. They are very resistant to changes in water conditions. But the point to be kept always in mind as a basic rule with livestock is not to cause any big jump in water parameters.

Feeding:

Amano Shrimps are omnivores. They mainly consume algae in aquariums but they will also not reject fish foods and flakes like all the other dwarf shrimps. While they are keeping in large numbers and the algae source is not sufficient it will be better to feed them with additional fish foods and flakes. The foods can be chosen which are offering both vegetable and protein sources.

Breeding:

In a home aquarium, it is not easy to breed and succeed in raising the fry. The young shrimps don’t hatch utterly developed. They are born as fry and require saline water to grow up. Fry also requires suspending algae in the water column to feed on and grow. After growing in the saline water, they must be transferred back to freshwater.
