Referred to in the hobby as Hydroctyle sp Japan, its true name is Hydrocotyle tripartita and it originates from South East Asia. The leaves are small and presents a brilliant green colour in your aquarium. It’s best to plant hydrocotyle tripartita as a carpeting plant as it hugs the foreground and sends out runners on a daily basis. If the light is dim, you may find it stretches up the tank. Good light is needed for the plant to form a lovely carpet along the substrate. Once you’ve taken hydrocotyle tripartita from the pot, you’ll be able to split the plant into several portions and plant into the substrate with tweezers.
