Hello! This is my first post in this forum, and hopefully somebody can help me with the issues I'm facing regarding my alternanthera reineckii mini's.
Just 24 hours after I planted it in my aquarium it melted away immediately. Look at the picture below. There are some reineckii's that are perfectly healthy that I planted with the DSM method 2 months ago. The tank has been flooded for 1 week and have good lighting, a lot of flow but currently no CO2 yet. Substrate is Seachem Fluorite Black and it's a 15 gallon tank.

This picture is taken just after the planting, about 24 hours earlier. https://imgur.com/a/Jr3OuLi
Couple of days later the reineckii's are almost completely gone: https://ibb.co/sRCQ4cG
Is this a natural part of the transition and will they eventually re-grow or what happened?
