Ok I think I've decided to go with the fuge rays. I'm also going to forget about the rainbows and just do geos, a pike, a chocolate and tetras with a couple BNPs. I picked up some rocks to build terracing walls, but I guess I need to cut some acrylic and silicone it behind/to the rocks and to the glass to make it leak proof. I'll read up more on that before I do it. Here's a pic of my approximate hardscape.
