Please could someone ID my plants, these are the plants that seem to be doing the best in my tank and flourishing;
This is the tip of the following plant, it is actually growing out of my tank, it was about 6 inches big when I got it about a week ago!!!


This one will be the next to grow out of the tank it has a new shoot at the very top

This one seems to be doing rather well, are the white "stringy" things new growths?

What is this and the brownish thing hanging off??

Thanks 
The light green with white fluffy growth is the very popular Hydrocotyle leucocephala or Brazilian Pennywort 100%.
I love this plant and have just placed one in a new tank I decorated. This is one of the faster growing plants I have ever seen. I have seen it grow 1.8cm in just 2 days! They grow like crazy in almost every water condition and are hardy survivors. If it is planted in the substrate and has good light, it will grow even faster. In a few weeks you can expect it to grow out right out of the water. It is a natural climber and will attach itself to the edges of your tank or float over the surface. It is ideal for small or newborn fish to hide. Don't worry, it is very easy to trim back as almost nothing you do to it will kill it.
The stalk with the one leave at the top, I have no idea. It looks like a type of Hygrophila (possibly Corymbosa) some go reddish under stronger light.
Finally the brown stringy things look just like the new shoots of Java Fern (Microsorum pteropus) which I think I can see some in the picture well covered in black spots
I recomend you google pics of these species to confirm all this thou... I may be wrong. Good Luck!
