One productive aquascaping weekend later...
I replaced all of them with smaller, darker ones. I think it looks much better.
The Limnophilia is way too stemmy so I trimmed it way back after i took the shot. I'm not sure I like it so I may replace it with a Rotala of some kind. (suggestions?)
There's one stem of E. Stellata and a tiny bit of Downii planted in front, hopefully they'll take off. I plan to use the Downii for a carpet on the left side.
I like the E. Tennellus but I think I need a mid-ground plant between it and the bogwood. Blyxa maybe? and move the long stems to behind the hardscape?
What do you think?
