I've just about made up my mind that the ludwigia has to go. It just has too many negatives:
1. Overall "messy" look, between aerial roots, side shoots and the occasional dropped leaf.
2. Needs constant trimming. It's not quite as fast growing as caulerpa, but it isn't that far behind.
3. Because of the constant trimming, I'm seeing an overabundance of side shoots wherever a cutting is made. While it makes the planting look nice and full, it also is starting to overshade the blyxa located in front of it.
I just don't know what I'm going to do in it's place. A couple things I've been thinking about are:
1. Java fern. It's tall enough, it's slow growing, it's indestructable, and I think it's leaf-shape would fit in well.
2. HM. It's not tall enough, but I might be able to coax it up to 4-6" height. Bushy, and would complement the HC already in the tank.
3. Corkscrew vals. Would need regular trimming, grass like leaf shape.
4. Cyperus helferi. Another tall, grass-like plant. Slow growing.
5. Let the blyxa have that entire corner, at the cost of the tiered effect that I have now.
6. No plant at all; put in a tall piece of driftwood in that back corner and let the blyxa fill in all around it.
Anybody got any thoughts while I try to figure this one out?
