I think your Buces aren't doing that great cause they attach better to rock, specifically lava rock, than wood. I would try that and see how it works. T hough I love the way they look where you layed them out, so it's a shame to have to move them. I also love the new branches and the placement of the Erio up front, you should add some more!! Also, I think the H. pinnatifida will look great once it grows in! What kinds of Anubias do you have in there, is it just Nana and Petite, or do you have others as well?
