Good news, after two months of growing my java moss it has trippled in size with only .75 wpg in a 20 gallon high tank. There has been a lot of dead stems though, it was all in a big clump so i spread it out all over the tank, now it looks like a carpent of moss. It will be hard to gravel vac but i am planning on getting more shrimp to help me out. Pretty soon i will have to give away some.
i have looked closer on my moss and found it is a hideout for baby shrimp :) hopefully most will survive and can get me some more cleaners although i have doubts since my tank has rams and crazy danios
