Ceratophyllum demersum "Foxtail"
Ceratophyllum demersum 'Foxtail' was found in a smaller tributary in Bolivia during an expedition to Rio Guapore, a boundary river between Brazil and Bolivia. Ceratophyllum has no roots as such, but it is nevertheless possible to plant it in the bottom of an aquarium and stems can become up to 80 cm tall and 5 cm wide. 'Foxtail' differs because its leaves are closer together and it has lateral shoots, which gives it an attractive, compact appearance.
The plant also distinguishes itself because it is hardier and its stalks do not break as easily as those of other Ceratophyllum-varieties.
