Panta Rhei’s “rafting” or “torrents” aquarium creates a raging rapids for river-dwelling fishes and sets the bar for all who aspire to create a true “river tank”.
Floating plants like Water Lettuce provide comfort and light-dampening security which are particularly important for breeding aquaria (especially guppies!). Their roots provide great shelter for small fry, and, of course, they make tanks look great from above!
Water ferns (Microsorum and Bolbitis), Bucephalandra and Anubias form the phalanx of what would be considered to be “fish-proof” plants. But there is yet another, not often considered alternative: Hygrophila pinnatifida.
This Southeast Asian specimen will grow out of the aquarium if given the chance, producing blue-violet flowers and a thickened, woody stem.
As a carpeting foreground plant, one can hardly fault Hydrocotyle tripartita ‘Japan’. This Southeast Asian import grows fast, low, and carpets densely in a uniform manner.
