Gotta have our priorities in order you know! lol... and yeah I started adding a thin layer of sand on the botton simply because the blue squares make me want to stab my eyes out.. lol and the fish seem to cluster around the small bit already with sand, particularly the rays and cat. The eel doesn't seem to really care and cruises around the whole pool with the gar, or picks a peice of DW to hang-out in. I would like ot get a few BIG peices now that I have the space to give the eel something more substantial to hide in.. BUt this thing is going to take monthes if not years to evolve into the picture in my mind.
It'll look a lot better wih sand! I got sick of looking at the blue bottom when I had mind, Catfish really seemed to enjoy the sand over the pool bottom. Had to make sure I didnt step on the pleco when I was placing more sand though
Good luck!
