Amano Shrimp are great for eating algae. When hungry they will eat hair algae and black beard algae as well. They grow larger than a lot of other shrimps and are more robust. A great addition to any planted tank. Most aquascapers will use many of these to keep the algae at bay. They’re called Amano shrimp because the aquascaper Takashi Amano uses so many of them in his aquascapes.
