I have had dwarf hair grass planted in my tank for about a month and a half. It has not died on me but it also has not really grown or spread out. I have a 10 gallon tank with 2 23w Cfl 6500k bulbs. I have CO2 running and I even changed my substrate from regular gravel to an Eco complete brand. Is there something I am missing or doing wrong? Like I said they are a pretty green but just aren't spreading out.
