Photograph of a floater of a Dwarf Red Lily (Nymphaea stellata) in one of my Community Planted Tanks. Floaters are not really very good for indoor glass aquariums. They just block the light and do not allow the light to reach other plants. Again, floaters are not actually visible from the prime viewing angles, e.g. front or side of an indoor glass aquarium. Again, while developing floaters, most of the plants do not shoot any new submersed leaf. However, I like to keep few floaters in my open top indoor tanks. They look pretty nice. But, floters should be monitored and cleared on a regular basis, to ensure that they do not cover the other plants from the light.
