What should I add to my fish room?

I just purchased a new home and I'm going to be building another fish room in the basement. This weekend we're planning on redoing all of the plumbing in the basement. There is a mixture of copper and galvanized steel for the water pipes so we're just going to redo it all with copper.



I figured now would be a good time to rough in the plumbing for the fish room as well. I'm just wondering what you guys think I might need plumbing for. All I can think of is RODI and maybe a tap with a hose on it so I can wash the floor. Can you think of any other plumbing that I might need in the fish room?
