    Healthy plants

    Healthy and good size. Out all the plants that I put in my aquarium, this one melted to nothing and hasn't come back. Not the seller fault. The shock of different aquarium conditions can cause plants to melt.

    A little color, Please

    Posted by Glenn Starner-Tate on 1 Oct 2021

    And this was added for color - other than green - in my planted aquarium. I'm a newbie to plants and so far everything is perfect. This was another great addition.
