Bright lighting is essential for good cultivation.

Plant care

It is advisable to carry out regular pruning to prevent it from bending once it reaches the surface and then go to shield the light for the underlying plants.

Water care

Egeria najas is very suitable for tropical aquariums, where it grows even at fairly high temperatures (optimal 15-26°C). Soft or medium hard water is recommended.
