Hi again. I was thinking of having live plants in the biube pure after hearing they are very good for cycling and provide natural cover and a tasty snack for some fish. The problem is that the substrate is marble sized (literally) and most plants need finer substrate. I cannot remove the media and use a different substrate as the biube is designed to filter and work with this special substrate. Please comment on what plants if any are good for the biube as I would love to have live plants and they would be better for the fish. Thanks again.
