Hello. I have just got some hygrophila siamensis 53B from tropica 1-2 grow. When I removed them from the packaging all the stems and leaves had gone a dark green slime like. After removing the tissue thing from the bottom I was left with just the roots and a tiny bit of stem left so I have planted them. Does any one know if they will still grow or should I remove them so they don’t rot in my tank? Thanks.
