I was doing some searching here to try and find an alternative to using grapevine. I currently have 1 piece of grapevine inside my red eye tank and in only 2 days it has mold growing on it. Is this because my air flow is not good enough or simply because it is not a good choice for my tank. If it is not a good choice for my tank, please lead me in the right direction for choosing a decorative piece of wood. If someone else has had success with grapevine, how or what did you do to prevent the mold/mildew? Thanks
