Beautiful pic ! and not just a mass of washed out blur remind me what camera you use again ? I saw a link you had a while ago - the link has obviously expired at whichever shop it was.
Nice photo Jimbooo. I love cardinals I got 9 of my own now but I just get blurs. They swim too fast and I dont know how to use my camera. Need a fast shutter I guess.
look at the bottom cardinal, the one facing you, his nose is pointing at Riccia Fluitians, the clump to the right (his left) is dwarf riccia.
you cant see much difference in the pic. both plants as you know are made up of small individual strands which make up the mossy structure (lots of bits tangled and entwined together)
a strand of fluitians is about 2 inches long with 2 or 3 branches. hence when it grows it looks like a garden lawn. Dwarf is more like a snowflake structure, more round rather than long. hence dwarf grows into a bush/hedge rather than a lawn.
