Re: How giant is Giant Hairgrass ? My tank is 24" tall and the giant hairgrass reaches the top and then is spread about another 8" across the surface. It's probably a bit much for the tank you have. I find it doesn't propogate as fast as dwarf hairgrass but can become just as invasive since it spreads by underground runners. New shoots will pop up all over your tank if you don't control it. |
