I bought 2 ready-to-plant waterlilies from walmart. The seeds are in a mesh bag with some muddy substance surrounded by coco fibre. The coco fibre is supposed to keep water clean. The lilies are meant for a pond but would it be ok in my aquarium? Would the coco fibre change my water parameters too drastically? Is the coco fibre safe for my fish? Are water lilies a poor option for an aquarium?
