I have gobs of this plant (
http://www.plantgeek.net/plantguide_...search=frogbit .) It's a floater that sends down roots-great for fry or fish that like to hide/play in plants.
It grows well under medium light; I give mine Flourish Excel daily, but that's it. I am a plant moron and it grows beautifully even for me!
These plants are in a tank that has contained snails; there haven't been any in there for several weeks, and no adults present for a couple of months prior to that, but if you hate snails let me know and I will examine carefully before shipping.
Please PM if interested; shipping cost only, and trades considered too. I'm doing some shipping this Tuesday and would love to send them at the same time.
