I just set up my new indoor pond. I lined it white because it showed off the fishes color really well. Here's what I have in it: 2 gourami, a silver arowana, 2 angelfish, 3 assorted cichlids, and a betta. I thought the lily really added to it well and gave the fish somewhere to hide. How would you do the filtering on something like this? Here's the pics, enjoy!
