Need help with buce

I've recently ordered buce online and they came in after 2 weeks. Originally ordered 10 pieces for a very very good price but sadly only 6 full plants made it along with 2 rhizomes without leaves. They came in pretty bad and I badly need advice on making sure they make it since these are my very first buce plants

I think the best you can do is have them attached to hardscape and ensure the rhizome is not covered. If possible have them growing beneath another taller plant so it has some shade as too much light wil only attract algae on it's leaves. Its a slow grower, very much like anubias, and they dont appreciate a lot of light. Like with all plants make sure there's good flow and consider using a liquid fertilizer
