I'm setting up a new tank but don't have a clear idea in mind. I was planning on a riverine type of enviroment. The substrate is going to be gravel and rock so I don't want rooted plants. I was also thinking I wanted to try to get the look of plants growing right at the shore and spilling over. I have seen people glue plants to suction cups to stick to the back andwill utilize that strategy. Does anyone have a good idea or example to help me along? Or just good plant ideas.
