My little clumps of Crypt parva are spreading well in the lightly shaded part of my high light tank. In the open they weren't doing well. I think that if you have the patience, they'd be a gorgeous carpet plant. I also have another crypt I can't identify that's staying about 2 inches in diameter and has been sending out runners making a bit of a carpet.
I guess i have what might be called a 'carpet' of wendtii. I have about 30-40% of my
75gal planted with this crypt.
They don'y hug the substrate but I like the look of it. There are still holes that need to fill in.
I will try to get a decent pick this morning for you. Biggest issue for me is they grow so slow
