So i changed the water for the first time since i received the plant 2 weeks ago. Before the change, the water was still crystal clear after standing for several weeks without any water change.
However numerous leaves started to discolour, it turned brown and fell off. During the loss of old leaves many new green leaves with light pink speckles on them have started to grow. The quality of the plant is not great at this point in time however, it is still continuing to grow.
