Looking for a ground covering plant for a 10G RCS tank I'm starting. I first thought to use Java or Christmas Moss, but I here they can grow really fast and get out of control quick. I don't want to be in there trimming every 2 or 3 days to keep it looking good, and I think they will grow too tall for what I'm looking for. The Fissidens splachnobryoides has the shorter look that I like, but what I've read about this plant so far doesn't sound promising. Too much debate over being true aquatic, and problems getting it too grow. So I'm looking for something that stays pretty short, and spreads out at a medium pace (maybe needs a trim every couple weeks) to creep along the substrate.
Tank Setup will be:
10 Gallons
2 x 13W CFLs = 26W sitting right on glass top
(Light only needs to travel through 6-10 inches of water
as it will be growing down a rocky hill, between the rocks)
Should have CO2 before getting plants
Flourite Substrate
No Ferts
Anything you guys can recommend that fits this description and will grow in this setup?
