Short Description

This is a very hardy plant with tough leaves that fish will not eat. This makes it ideal for adding to a tank full of herbivores. The leaves can be trimmed back at the water surface if they get too long, do damage will be done to the plant by this. They do require plenty of nutrients in the water and they prefer the water to be clean as well as the substrate.
