Maybe you'd expect me to be snide about fake rocks. After all, there are those plastic rocks that snap together like a Lego kit to form gravity-defying Rococo fantasy structures rivaling the ormolu rockwork of a French mantel clock, or the setting for a Road Runner cartoon.

At your local fish store you'll see various kinds of rocks, all guaranteed "aquarium safe." At your local landscaping outlet or stone yard you'll see many of the same kinds, not guaranteed "aquarium safe" — but spectacularly cheaper by comparison.

In my very soft water, a large snail shell in a 10-gallon tank helps provide some desirable pH-stabilizing buffer, but it rapidly loses its decorative outer layer.

Pots make fine caves for lurkers and cave spawners. Cutting terracotta pots for aquarium use without smashing them to useless shards with a hammer takes some finesse.

What's the right rock for your aquarium? Everyone you ask seems to be undermining your confidence about what kind of rock is "aquarium safe."

Rocks with a calcium carbonate component — the "lime" in limestone — will raise the pH of the aquarium water. Unless you're looking for this effect, as in an aquarium of Rift Lake cichlids, you probably want to avoid it.
