hi i got a ball of some java moss that was floating in the back of a tank at my lfs it was not even labled they just gave it to me because i pointed it out. i spread it out and anchored it down to my drifwood. it appears to be attaching itself but over a week i have not seen any growth really and it is partly brown or dark dark green. nothing like the spreading like mad deep green stuff i see in pictures of others tanks. any ideas? should i just give it time? i have co2 and 96 watts on a 29 gallon tank. another question is alot of my rotala is growing sideways and sending down runners is this normal?
