that looks great! and it will give a nice open spot for you to see your fish when its all filled in with plants. I like this last arrangement alot. I like the dynamic placement of hte largest piece and the balance of the two smaller pieces.
Now, it looks great! That did it for me. Maybe in the now more open wide spot between piece 2 & 3, you could do some hairgrass for a meadow like affect, kind of oblong/rounded, running from the back to the front left.
yep, I was having trouble with the big piece on the left of the first post and would have suggested you point the opening of it more to the right or the center of the tank but I think removing it all together did the job...
I agree w/Dangerdoll, after you removed the simple left side piece it looks well set. I love driftwood too, and it's great for the ph of the water. Are you thinking of planting it w/real plants? And what kind of fish are you thinking of? Can you expand on your point about 1.6 ratio to 1 re: center piece? I'm not sure what your talking about, but sounds interesting. thanks
