I understand completely how you feel. It seems I am always changing the decor in my 80 gal Dempsey tank. At first, I googled.. "photos of cichlid tanks" and a couple of sites popped up which gave me an idea of what I would like for the tank to look like. I belive they were cichlid forums with photos of different members tanks. I then went to lawn and garden stores searching for suitable rock. I chose slate and flagstone having no desire to alter the alkalinity of the tank. I also utilized large pieces of driftwood which helped with the look I was trying to create. Large ,.smooth,and rather flat river stones were also used to help support the slate and flagstone. I sadly, am never satisfied ,and am always rearranging the tank it seems and each week,, everything comes out for gravel vaccuming.
