Just going to shoot in here, i've a feeling i might not have the exact ones you are after, i've been studing the pictures (well looking at them on my pc and not laptop lol) and they look slightly different, mine have les curls in them, heres a picture of them,
and excuse the other plants alot need help XD but there is the small ones i cut away from the mother plant in this tank,
although there all healing well, im afraid i may loose some so if your still intrested in these it may be a few weeks before there growing nicely again, atm the dead or really damaged leaves are slowly dying of, i may even loose them all....but on the other hand some do look like there on the mend! im just so unsure atm!
but back to the qeustion these are different right?
