in the short future i am hoping to use bolbitis and needle java. I wanted to use it in the way that amano uses ferns. when amano uses them they seem to grow horizontal to the substrate which i like the look of. most of the aquascapes i see ferns in allways grow verticle. does anyone know how amano does this? is it the high lighting he uses? i have been thinking over the past few days and i can think of exacly why but have allways noticed he uses them in crevices or under rock edges. maybe this is why they grow this way. if the rizhome is under the edge of something it has to grow horizontal to get light. what are your views?
