I agree with blackwidow re: that temp seems to be a pertinent parameter...I have java moss recently purchased from two sources, one is my LFS (the largest on the east coast-by their advertising) the other by mail order. I divided moss from both into my two tanks, but 3 weeks later some new-ish cardinals had ich into one tank, so I increased temp to 85 degrees F there nd used API Super Ich Cure for 4 treatments instead of two.
I also have a segment of the mail-order Java Moss from the mail order shipment in an open bowl in a sunny window, temp ranges from 60-78 degrees F during the course of a day here.
Results: the java moss in both fish tanks (20 g long & 20 g tall) had a few greenish sprouts, but lots of brown (within a week of moving here). The window-bowl is bright green and moss increasing in volume. Never a hint of brown there.
Now, going to observe the cardinal/ich tank at its high temp (85-86 F) for over a week... with the increased temp, the Java moss look amazing, lots of new rich green--more than anywhere else by a mile. It is not the only plant to act this way; my bacopas now reach the waterline, anubias and crypts are going nuts.
I thought increased temp was a big issue for these plants-guess not???
My feeling is that if Java Moss may need a certain level of hands-off...too much attention and it fails. Just my thoughts and most still a mystery!
