Blyxa japonica is an obligate aquatic plant often found in stagnant, shallow pools and marshes as well as in slow moving, iron-rich forest streams in tropical eastern Asia. It can also be found in man-made habitats (such as rice paddies) throughout its range. It has become a staple in the planted aquarium hobby due to its attractive grassy, hedge-like appearance and should be easily obtainable from many internet retailers or through trading. This Blyxa species is not too difficult to grow if its basic requirements are met: intense lighting in the 2-4 watts per gallon range, CO2 injection, and a fertilization regimen including nitrate, phosphate, potassium, and micronutrient supplementation. If conditions are to its liking and lighting is intense, the leaves of B. japonica will develop golden and reddish hues and the plants will exhibit more compact growth. If it does not receive enough lighting, however, B. japonica will become taller, lankier, and greener. This plant produces an impressive root system and appreciates a nutritious substrate. If phosphate levels are kept high (1-2 ppm), this species will continuously produce small white flowers on long, thin stalks.
