Ceratophyllum demersum (also known as Hornwort) 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 can still be planted in the bottom of an aquarium and stems can become up to 80 cm tall and 5 cm wide. It has lateral shoots, which gives it an attractive, compact appearance.
Note: The picture shows a lead weight at the bottom of this plant - we do not send with this as it can damage the plant during transit. So when the stems arrive with you simply push them into your substrate with tweezers so they are about 3cm deep. In addition, as it is a true aquatic plant there are chances of snails or snail eggs. As we buy from European stock, pesticides are never used. Whilst we do our very best to remove any that we see, we wanted to make you aware that this is a possibility.
