We keep a variety of floating plants here at your local fish store! Salvinia, red root floaters, frogbit, dwarf water lettuce, and more. We don't stock duckweed. These are brought to us for store credit from walk in customers and we cannot guarantee no snails or algae. 

What we have in stock is always changing, we will supply " dealers choice " based on what we have at that time. If you require a specific floating plant and want to be sure no sails or algae we recommend looking at the Tropica Tissue Culture floating plants we carry. 

Great example ! Red Root Floaters
