I'm guessing your not a fan of amano type tank set - ups?Java moss would grow in a mud puddle. So you will be fine
I see you have a moss ball in the pick also, do you squeeze them out as I have read? Or just turn them occasionally as I do? Sorry if changing the subject.@phantom
Yes, Java moss is one of the first I tried when I started. I tied it to a piece of slate. At first nothing then started to turn brown. After 3 weeks I was ready to give up and toss it but then it started to grow. See Before and After. Not the greatest pics but you can see the growth after 6 weeks. Hope this helps. Good Luck.
