I'm getting some Java Moss and I wondered if I need to know anything about growing it. I have corys (they should spawn in the next couple days in the tank I'm putting the moss in) and soon RCS (they are coming with the moss). My tank is sanded, not gravel. I don't want it to get out of control, as I like my tanks tidy. I'm probably going to tie it to a 8 inch tall rock I have and try to keep it off my fake plants. Should I even bother?
