More, smaller rocks to make more holes and caves. If you don't have a LFS you can order online. Petco & petsmart, like said eariler, is what it is. They try to sell everything w/o really specializing in one department. If you have problems w/them stop buying their stuff. I am in the boat of supporting LFS and not the big box shops. For some it is not an option and to those people I say QT. I buy my dog food at a Petsupplieplus and always look in their tanks. I have yet to see a fish that I really want or need. The tanks don't look that good and the fish not any better. That said, it just comes down to them being understaffed or undereducated and having a nice fish department. They have a lot of balls in the air over there, so evrything can't be looking good all the tme.
