Yeh prob a crypt of some sort, its very hard to tell exactly there are 100's of types. Generally they are undemanding plants but root tabs or a plant substrate help as they tend to be heavy root feeders.
Themuleous, I'm shocked it's growig at all. I move it around all the time, I never give it anything and it's got so little light my java moss is dying even. And since its sprouted, it's grown another leaf! But now that I like it, I'd like ot take better care of it. What are these root tabs and where can I get some?
I know this is a UK website, but the root tabs are things like this and this, other ones are shown here. I have found the seachem ones to be very good. I would try and get a general one, ie that contains lots of different nutrients rather than one that just contains iron
