The favourite in the aquarium hobby Thai water friend Hygrophila corymbosa ‘Siamensis’ is a classic aquarium plant from Southeast Asia. The fast-growing stem plant, can be used optimally for algae control because it is undemanding and consumes many nutrients that are thus no longer available to the troublesome algae.

The Thai water lover branches up nicely with regular support and then becomes bushy and compact.
