Aquascape DIYAmano Shrimp Caridina JaponicaAquarium Designs

Takashi Amano is a photographer, designer and aquarist from Japan. He was very influential in the world of aquascaping community. His work that uses rocks and woody has a very high artistry. Takashi Amano also popularized the aquarium plants such as Glossostigma elatinodes and Riccia fluitans to decorate the aquarium.

In addition to the types of aquarium plants, Takashi Amano also popularize Caridina japonica, which is a very effective type of shrimp to eat and controlling the algae which growing on the aquarium plants. The types of algae shrimp is then called as the "Amano Shrimp".

When he proves that this shrimp was effective to eradicate and controlling algae growth in large quantities, then Takashi Amano bought thousands of Caridina japonica shrimp from aquarium supplies in Japan. After that, Caridina japonica or "Amano Shrimp" was as a necessity to all of his freshwater aquarium.

Another advantage of the "Amano shrimp" species is, although put this shrimp into aquarium in large number, they will not look too much or looks meet the aquarium so it does not interfere with views of the water plants decoration.


Due to its large appetite for all kinds of freshwater algae, Japonica Amano Shrimp or Amano Shrimp has gained popularity among world aquarist, so now many are found in almost the entire aquascape aquarium as the natural algae removal. They will consume leftover fish food and detritus on the aquarium floor, making the Amano Shrimp an efficient cleaner that is also very interesting to watch. The Amano Shrimp is mostly opaque brown in color with a tan stripe that runs the length of the back. On their sides, there are many broken horizontal lines.

The Amano Shrimp is also known as the Yamato Numa-Ebi, or Japanese Swamp Shrimp and it originates from the swamps of Japan. The ideal setup for the Amano Shrimp is an established freshwater aquarium or pond of at least 10 gallons with plenty of hiding places and algae with a mature substrate. The Amano Shrimp should be housed with small peaceful fish or koi that will not pose the threat of eating it. The Amano Shrimp can tolerate low to moderate salinity levels, making them an ideal algae controller for ponds and water gardens in non-freezing climates.

Unfortunately, the Amano Shrimp is very difficult to breed, and very few hobbyists have been able to raise the larvae to maturity. The average life span of the Japonica Amano Shrimp is 2 to 3 years in captivity.

Japonica Amano Shrimp is an omnivore that will consume algae, detritus and left over food. Even if they can find food almost everywhere in the tank, once a week or so, feed Caridina Japonica with specific food or with fish pellets, some of them seem to appreciate a lot spirulina pellets.

Althought "Caridina Japonica" are known to eat algae, anyway remember the Amano shrimps are not a final solution against algae proliferation because they are too small and do not eat that much, moreover they like just some kind of algae and ignore others. The only one solution to algae problems is to control the aquarium balance, including lighting period and quality, filtration work, fish and plants number in aquascape aquarium.
