I'm trying to get started into planted tanks, and I'm going to do a low light, non-co2 tank. I want to use java fern and Anubis for the main plants, but I'm having trouble finding a good carpet plant. I would love to use dwarf hairgrass but I have read that it truly struggles in non-co2 tanks. I'm just looking for something that will serve the same function as dwarf hairgrass, but more low maintainence. I was thinking about maybe java moss or christmass moss but Id prefere a grassy plant over a moss. Any ideas?
