The UG has piled up and grown more aggressively than in the past. As such, it's not really a foreground plant for a long time frame nor is easy to keep that way in this tank.
I'll keep the bigger pile in the front middle section and then return to more group style with multiple species rather than a single foreground type.
It was well worth a try though with the UG. the problem side has always been the Left. I have Rotala macrandra there now, it'll grows very nice there, but it's a high current region, so it'll be all over the place. I'll move it to the rear behind the main tree trunk.
Some options for the last red row: Rotala butterfly, there's some at the end of the row , about 4 stems. Not sure if it'll do favorably in the row however.
Rotala sunset, I have some growing in another tank, problem: it does not like to be transplanted often which is required by this tank and the row in question. I can do it, but it's more work than it should be. Return the Lud sphaerocarpa back to that location. It does okay but is a pale red, I wanted something more intense. L peruensis does well,m but is very common etc and has the same color as the L. red next to it. I have L arcuata, but it's too spindly. L inclinata was okay, but gets ratty and grows too fast.
The search for the plant that goes there continues.
Some changes are afoot:
