I am selling frogbit, $1 per head. These will be the medium ones pictured, not the giant ones, or 3-4 small ones will sub for one medium one. They will probably come with a little bit of regular duckweed stuck to them, and may also contain various other life forms including but not limited to Malaysian trumpet snails, pond snails, water fleas, etc. I have found that the regular duckweed does not grow very well when frogbit is present, but your results may vary. These come from completely still water with very high intensity lights, your results in growing them in a tank with a filter and different lights may vary. I have about 10 heads. The roots, which are typically about 1ft long right now, may melt, but with proper lighting should grow back fairly quickly, though maybe not to that ridiculous length.
I am also selling large leaf duckweed. I don't grow this with the frogbit, so I don't know if it would grow very well with it. The large leaf duckweed is about 10-20 times bigger than the regular duckweed. This does not grow at all in my tank with a filter, and typically dies off in that tank after about a week. It comes from a tank that has a fairly large population of ramshorn snails and medium lights. Your results may vary. Price is $1 per teaspoon with a limit of 5 teaspoons.

The large leaf duckweed is pictured here with a baby betta from Petco, so no, it isn't THAT huge. lol.
Shipping is $6.50 for Priority within the continental US only. It is being shipped from CA, where the weather is always nice. Use your best judgement when your ask me to ship, as I don't really understand "freezing" or "snow". Live arrival not guaranteed. Trades for plant species I don't have are something I will consider.
