If this is the tropica one (which looking at Google pics it seems to be) then I used to have it in my nano when I first set it up. I found it very very very slow growing even in an EI tank. You're supposed to be able to detach the 'leaves' and reattach them else where in the tank and it should root, but I never managed it, mostly because it grows to dam slowly.
Oh yeah and it grows very slowly
PS - Did I mention that it doesn't grow very fast?
No Tropica sell Monosolenium tenerum, that is the ordinary version, although now that you mention it I do remember that plant in your tank alright and that indeed was Riccardia chamedryfolia. You probably got it from Aquaticmagic. I know a few people have grown this plant on the forum but have found it difficult, algae problems etc. I will probably buy some anyway and have a go at it. In the tank I have going atm I have ferns and bolbitis growing beautiful so conditions may be to its liking (unscientifically tested wishful/hopeful thinking anyway )
No, it was tropica, I got it from Aquajardin over in Gloucester. Go onto the tropica website and do a search for 003N they just haven't named it yet
Hope it works better for you. I did see in the shop some that must have been over a year old and it look stunning, the smaller leaf size is really attractive, mush more so that the standard Monosolenium
