Answer: Some of the difficulty your plants may be encountering is poor lighting, along with shallow water. The plants you've mentioned generally thrive in outdoor ponds and pools. Try to adjust the lighting by adding an artificial source, or by moving your fountain to a brightly lit area. In such shallow water you'll probably not have success with blooming plants, but you can try floating duck-weed or water Forget-Me-Not (Myosotis palustris) on the pool of water. There are also miniature primroses available, as well as tiny ferns. Your local pet store may have aquarium plants that you like. Good luck with your indoor water garden!
