Hygrophila polysperma

Hygrophila polysperma is one of the easiest and most widely kept stem plants in the aquarium hobby, producing pairs of small, oval, light-green leaves along rapidly growing stems. Its minimal demands and fast growth rate make it a staple plant for beginners and a reliable background filler in established aquariums of all sizes.

It grows vigorously under low light without CO2 injection and tolerates a wide range of water parameters. New aquariums benefit from Hygrophila polysperma during the cycling phase — its fast nutrient uptake helps control algae and stabilise water quality while other, slower-growing plants become established.

Supplied as an established potted plant, Hygrophila polysperma suits aquariums from 50 litres upward as a background plant. Regular trimming prevents it from reaching the surface and encourages the dense, bushy growth that makes it such a useful and visually pleasing background plant for any style of aquarium.
