Madagascar laceleaf has a reputation of being difficult. That proves your skills of a master.
I don't know about this one. I can't grow Eriocaulon at all. I've put the Madagascar Lace in, left it alone and it just grows and flowers. It's had a dormant period for about 6-8 weeks and came back strong. If its doing well, I try not to mess with it.
When I initially laid out the scape, I was trying to have 2 open areas for the rainbows to swim, kind of like a discus tank. I had that till it got over grown but not totally happy with it but haven't come up with an idea.
Thanks for looking.
