This was a wasted purchase, I am afraid. It won't fill in as a carpet, grows very slowly, and is vulnerable to algae because of that, yet it requires higher light than other crypts. As a midground option, it's too small. I won't be using this plant again, but I was wondering what others' experiences were with it. I imagine it would look good in the midground of a nano tank that has baby tears as a foregroundlawn , but I have seen picture of downoi as the midground with the tears, and that combo is pure perfection. As bad a choice as the parva was for me, my dwarf saggitaria is growing as a great midground plant, bringing the whole tank togther. I went with glosso on one side and microsword on the other. But, on the micorsword side, the dwarf sag is multiplying towards the front of the tank. I have been planting the babies in midground areas all over the 55g tank. Once I resolve my lighting/algae problem, and my 3 plant levels (fore,mid, back) reach maximum fullness (they are almost there!), this tank will look awesome. What a long strange trip it has been with this tank...
