In the wild

Overview

The Amano shrimp actively explores plants and decor to pick its food from them. Females grow clearly larger than males, whose abdomen bears a pattern of small dots. It stays peaceful, but its size does not protect it from large predators.

Scientific name
Caridina multidentata Stimpson, 1860
Classification
Decapoda › Atyidae
IUCN Red List
Least concern (LC)

Natural habitat

Japan (including Kyūshū) and Taiwan

Observations (GBIF) and localities Native countries Rivers and lakes

The adults live in fresh water, at 16 to 28 °C, neutral to alkaline (pH 7 to 8.3). The larvae need salt water to develop, before the young return to fresh water.

Behaviour

Peaceful and rather calm, it lives in colonies on the bottom and is active by day, tirelessly exploring plants and decor. Being small, it hides when larger animals are around and ignores other species.

In the aquarium

Care and setup

Keep it in a group in a tank offering plants, roots and refuges for moulting. Avoid fish and crustaceans able to catch it.

Feeding

It eats algae, microorganisms and plant matter, and accepts shrimp food. Do not rely on it alone to clean the tank.

Breeding

The eggs are carried under the abdomen. The larvae need salt water, so eggs laid in fresh water do not guarantee viable young.
