For those of us fortunate enough to keep glofish you might want to add some plants that look natural or would fit in with these glow in the dark fish. Sadly there are no live plants with these properties. Use a 55 gallon tank for this setup. For lighting, use black or blue light to bring out the colors of the fish. The best substrate I would use is a glow in the dark gravel if you can find any. You can use artificial plants, for best results, use plastic plants that glow in the dark. With this setup, you can create a "natural" glofish tank.
