Water Spangles (Salvinia minima). A grate floating plant. It's dangling roots, which are a great feeding area and refuge for aquatic animals and fry. Also grate for absorbing excess nutrients as are all floating plants. This hardy plant propagates quickly and can provide shade to areas of the aquarium, which will encourage more reclusive species to come out of hiding. I also have Water Lettuce and Amazon Frogbit (floating plants). As well as other aquarium plants. Cash please, I don't have any of those apps. Sorry for the inconvenience. $10 for around a hand sized amount. Check my other adds for other plants.
