It's been a month now and the java moss will not attach to the gravel because my fishies keep disturbing it. I don't want to deal with covering the bottom of my tank with mesh because I have so many other plants in there that I don't want to disturb. I was thinking about going with dwarf hairgrass, mainly because its all have have seen around here.(although I haven't paid much attention yet) So I'm just wondering about the general care of hairgrass, like WPG, any ferts, ect.
