This is the submerged form... The plant curled down but did not melt... New Greenish growth can be seen... Been in my tank for more than 3 month... =)

it looks like quite different from the emersed form. But interesting!

The pattern looks like flame moss to me...

I've put in a flower pot and it doesn't grow for some reason. Weird.

Moss normally do well in humid environment, maybe that is why it does not grow.
