Popular Algae-eating Shrimps
One way to keep you tank algae-free is by having shrimps. Among the popular ones are Yamato Numa Ebi (Caridina japonica) and Red Cherry Shrimp (Neocaridina denticulata sinensis). They all can tolerate a wide range of pH but are very sensitive to ammonia level. If excessive fish food is available, they will choose to eat it over algae. A 10 gallon tank can be handled by a team of 10 or more.
The popular Yamato Numa Ebi is often referred to as Amano shrimp. It reportedly lives longer than other types of shrimps. It can grow to a maximum size of 2” and is light brown to opaque in color. It consumes a large amount of algae in the tank, especially soft algae, but it will not eat Black Brush Algae. Sometimes it even nibbles on soft-texture leaves.
Red Cherry Shrimp from Taiwan adds a beautiful color to the tank. Its red color depends on several factors such as mood, water condition and food. Egg-carrying female becomes very red in color while male tends to be much paler. It works great as an algae-eating machine, but is harder to come by.
