floating plant ID help please

That's really pretty! Does it stay that size or get larger? I like it.

I definitely agree that it is a ceratopteris of some sort. Although, I bet that plant is baby ceratopteris pteroides. If it is it will eventually grow fairly large with leaves raised above the surface.

I have some Ceratopteris pteroides. During the winter when it gets less light mine stays around 4" across. When it starts getting more light it revs into high gear growing over 12" across and the leaves change from solid to highly branched. Luckily it will have a bunch of baby plants I can detach from the edges of the leaves so when it gets too big I remove the monster mother plant and keep the babies.

The correct name of this swimming water sprite species is Ceratopteris pteridoides (not pteroides).

thanks I was a little confused about that.... Have a great day!!!

Now I've found the spelling "pteroides" in the plant finder, but I think C. pteridoides is correct because it is used in botanical literature: http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=200003557

Hmmm... That's probably correct. I know a fern guy and will ask him shortly. All indications seem to say that you're right. Curiously, IPNI has it both ways:

thanks a lot.... I love this stuff it is going nuts in my tank

I've fixed it for now and likely won't be changing it back (thanks miremonster). I would like to find out what the deal is with that IPNI reference, just to see.
