Well, I have a heck of a head cold..why I seem to start these projects in times like this, I am not sure..but this morning, I totally redid the tank. No, not quite true, I supervised while my poor husband had to "move it a little to the left, no, a little back..) you get the idea. BUt after asking you guys how much room you had between rocks and the back glass, I figured it should get done. The placement of the rock looks nice enough, but now I have 3 feet of bare naked sand in the front. Any ideas of what I could do with this space? The fish have tons of swimming room.
