Alternatively, you can't go wrong with a mix of fine gravel and sand (light colored), some slate and a few nice pieces of drift wood.
Went to every Petco around. The lime green must be in-demand. Was sold out everywhere. They did have 1 bag of rainbow left, but sadly the solitaire bag wasn't enough.
