According to this article, Amano is the most efficient algae eater. Do you agree.
Caridina Japonica is extremely beneficial to any aquarium simply because they are the best algae eater. Their larger physical size (two inches) makes them able to eat algae that most other shrimp or small critters cannot. They are also very easy to care for but difficult to breed.

An experiment – Amano shrimp is the best green algae eater?!
Some time ago there was an experiment – who is the best green algae eater? Amano shrimps, fish and snails were left to graze on the tiles with green algae for a period of time before the tiles were removed and analyzed.
Regardless of how the grazing rate was expressed, the Amano shrimp was the most efficient grazer on the type of substrate offered in that experiment. When the grazing was expressed as the rate per animal, the Amano shrimp was 7-fold more efficient than the
Red cherry shrimp but only 2.4-fold more efficient than the Siamese Algae Eater (SAE).
However, since the Amano shrimp is a relatively large shrimp, some of the difference is caused by the fact that a large animal, in general, consumes more food per time unit as compared to a much smaller animal such as the cherry shrimp.
And so, if the grazing rate instead is expressed per gram animal, the Amano shrimp is only 1.8-fold more efficient than the cherry shrimp. For the SAE, it works the other way around as it is bigger than the Amano shrimp, so the difference in grazing pressure is 5.4-fold when expressed per gram animal.
And so, the study was very conclusive in the sense that the Amano shrimp removes much more algal biomass per time unit. The Amano shrimp is the best algal-eater among the candidates. It is the King.
