Amano Shrimp (Caridina multidentata)

The Amano shrimp will be ok with any range of temperatures and can be kept outside in garden ponds in frost-free areas.

They can be kept in either a species only or a community tank. The tank should be heavily planted and contain lots of hiding places for them.

They are a hardy shrimp that makes it ideal for beginners looking to experiment with invertebrates for the first time. Amano Shrimp are good algae eaters and aquarium cleaners.

This species has an elongated body, is glasslike, covered with a broken line of reddish-brown on its sides, and the back surface has a white stripe that runs from the head to the tail, and the eyes are black.

Amano shrimp have a calm temperament.

Supply them with plenty of places to hide, using decorations and plants; this will improve their confidence. Amano shrimp can be somewhat cheeky too, stealing food right out of the mouths of their tankmates.

Amano Shrimp

Natural Habitat

The original species of Amano shrimp came from the Ogasawara Islands, and people believe that Amano shrimp only came from Japan and its immediate vicinity, this is far from true.

In reality, Amano shrimp have also come from Taiwan, the Ryukyu Islands (between the Philippine and East China seas), Fiji and maybe even Madagascar.

These shrimp come from the streams and rivers flowing from mountains into seas and oceans.

They can also live in marshes and swamps.
