sparkyjoe, it does grow slowly - but surely.
And yup, I was surprised, too, lol, when I went to rinse my silk plant and there was green stuff stuck all over it..
aokashi, I can see it growing into a sort of little tree, lol. Just don't expect it to attach in a hurry, it took mine a few months to really start attaching to stuff.
What I'm finding really interesting is that it's attaching mainly to the underside of the silk plant, and thriving in the darkest corners/shade of other plants. Maybe it's truly a low-light plant, in that it prefers deep shade? Worth researching/observing a bit, I think.
I'll try to put some pictures up this week of how it's doing.. it's just in awkward corners of my tank for photos, but I'll work something out.
Here's some info from mizuworld's website:
It is in fact a thallus (plant body) of the Fern, Lomariopsis lineata. It is also referred to as Loma Fern for short.
This jelly-like plant closely resembles Pelia. It can be kept in low light tanks easily and grows well with or without CO2 supplementation. Due to its rounder growth, it is nicknamed "Round Pelia".
It is not very demanding and can do well even when placed in poor lights. However, the water temperature should not be kept too high. The growth is larger and rounder than Pelia and can eventually grow into a very tight bunch. Under low light conditions and even without CO2 injection, growth is more stringy.
"Loma fern" sounds pretty - but I think I prefer 'susswassertang', kind of sounds neat!
