I just got a few frags of kenya tree from a friend. They are opening up, but not standing up like when i took them out of his tank. He only had t5 lights and i have metal halides. Could this be why they are not acting right?? I also got a 4 in leather stalk from him that was floating around on the bottom of his tank not doing well at all. I put it in my tank and it stood right up and opened up. It has a bright green tint to it under my halides. It has some small polyps coming out a little, but nothing like i have seen in some pictures. Any help with that one will be appreciated as well. Thanks everyone.
