Water, mountains and rock formations. They're beautiful to look at, but are more than eye candy in an aquarium. Rocks and 80 pounds of live marine sand that contains live bacteria can mimic a natural sea bottom and conceal pump tubing while also providing places for your fish to hide. Just like people, fish need their privacy. Be careful -- precariously balanced rocks may look beautiful, but if disturbed can squash slow-moving fish.

$140: 80 pounds of live marine sand

Running Tally: $2,307
