plant id: Ceratopteris or terrestrial fern?

cheers, that's a relief!

i'm a lot more familiar with terrestrial ferns than aquatic..

is this the planted form? how long do they take to convert to floating?

not sure what the question is asking.. but what you do is plant the bottom in substrate and have the plant grow lol.. the plant isnt a floater like frogbit/duckweed/hydrocotyle.. but like any stem plant it can survive floating

my water sprite grows gangbusters floating, or slowly languishes and dies planted in the substrate.
 
It doesn't convert, but new plants which form on the fronds can be left as floaters. Personally I find it grows like a weed planted.
 
Well it's a fern, so I don't know if you can really call it a stem plant?

I'm pretty sure that it is often grown as a floating plant, but that the fronds take on a different shape when floating than when settled. At the moment it has fairly sturdy squarish stems, which to me look like a planted form.. or a terrestrial fern

KarlTh: Cool, i'll leave it floating until it has some new growth, then cut out the older parts
