fishfishfish, there actually are a number of natural holes in the big piece of driftwood but you can't really see them in the pictures. i'll often go a day without seeing one of my cories and then i'll see him coming out of some place in the driftwood that i didn't even know was there. my only worry is that someone might get stuck in one of those little caves one day.
thapsus, there is actually a really big piece of slate rock screwed to the bottom of the driftwood because that is the only way i could get it to stay down. that slate is against the bare bottom and the gravel is covering it.
i have changed many of the plants around again and added some more, bushier plants to the back to cover up the equipment. it's looking better but i'm getting worried that the constant change and arms in the tank are stressing out the fish!
