You have given me a great idea, I'm currently looking for driftwood, and have access to some old hardwood, but it's all fairly straight. Most of what I've seen in tanks has been gnarled and branchy. I really like the looks of your Java ferns attached to the straight boards. I love the moss wall growing in the background too, and am jealous of your hair grass... I just can't make myself pay $8 for a small square of dwarf hair grass at the LFS since I'm a newbie to all this, I feel like it would be a waste...
In any case Beautiful tank! I love that puffer too!
