A few weeks ago I was in a garden center looking at the selection of bog plants when these tiny little plants caught my attention. When I asked about them the garden center guy knew nothing about them except that they grow like duck weed and fish eat them. He gave me some and since then I have been trying to figure out what they are so I know how to look after them.
So far I have figured out that they are a "floating fern" which seems to be a catch all term for roughly fern shaped floating plants.
I have a picture but it isn't very detailed so here is a brief description. Leaves are oval shaped, well actually kind of hard taco shaped and they have tiny little hairs that look something like the hairs on a sundew, the picture should describe the rest.
Any information would be very helpful
