At Red Eye Aquatics, Ambulis is great because it does all the work for you. Simply plant one cutting in the back corner of your tank. It will eventually root and start spreading by runners throughout your substrate. After a few months, your tank will become a lush jungle with fish weaving in and out of all the bushy leaves, plant is easily trimmed if overgrown to make new cuttings . We love how it grows so quickly and uptakes a lot of nitrates. Plus, it's easy to remove if it's spreading somewhere you don't want it to. Just pull it out of the gravel and replant where you want it. It doesn't even need roots just cut a piece off and plant.
