Your choice in between Java moss and Christmas Moss or Christmas Tree Moss

Christmas moss (Vesicularia montagnei) has been gaining it popularity over the years. Base on my knowledge, it was made well known by aquarium hobbyist in Singapore. Perhaps there are 3 main reasons that it is becoming so popular, and many are taking it as a better alternative to the well-known Java moss:
1. It forms a very neat moss wall (if it is cultivated with a proper setup Moss wire mesh), with the moss forming a Christmas-tree-like shape
2. Christmas moss grows slower, so lesser maintenance effort is required. For Java moss, if you let it grow freely for 3 to 4 weeks in your tank, probably your tank will become unpleasant for your sight. As for Christmas moss, it could stay well intact and neat for at least 7-8 weeks. That’s half the effort to maintain, in short.
Some facts about Christmas moss:
Common Name: Christmas Moss, Xmas Moss
Scientific Name: Vesicularia montagnei
Temperature: 65F-77F
pH: 5.0-7.5
Light: Low (1.5WPG) to High (3WPG+)
Growth: Slow
Difficulty: Beginner
Christmas moss could grow beautifully in the aquarium tank with very high lighting, and it could also grow very well in the darkest corner. It is not too demanding over the lighting or pH, but in order for it to grow well, it has to be kept in the soft water.
The best temperature for Christmas moss would be arpund 24 to 26 degree. It could survive well in the range of 18 to 30 degree, but the growth rate will be slower.
All these behaviours of Christmas moss got to do with its natural habitat - waterfall area in the dense tropical forest. The sun are shining throughout the year, and the temperature could grow very high (more than 30 degree) at times. During the monsoon season, it is almost raining everyday and the temperature and sun light drops significantly.
Very interesting moss, let me know if you wish to get some samples! =)

How high does the moss grow? I’m looking for one that doesn’t grow high.

Star moss (Tortula ruralis) or Christmas moss will be excellent for you - they will grow horizontally (not upwards) and very easy to trim because they are naturally neat.

I recently added some christmas moss to my tank and it looks so beautiful. However, recently, they have started to yellow in some spots. I’m wondering what the cause is. I add iron twice a week along with various other supplements. I use a T5 powerglo bulb which has been good for the rest of my plants. pH is 6.8, temp 79~81F. Am I boiling my moss?? I keep tetras and bettas, hence those parameters. Any thoughts?

The temperature and pH is fine for the moss - it is able to survive. However I guess that you will observe a slower growth. However, the moss will be good for the water condition for the betta - read up more over here: Improve water condition with moss
