Build somewhere worth looking at.

A folded globe of ridges. Grooves run all over it.

A cluster of open pipes, each one breathing.

One huge cup. Small fish sleep down inside it.

A coral grotto with pale branching tips and a sheltered centre.

A flat mesh held broadside to the flow.

Branching antlers with pale growing tips.

A single fat stone. Catfish sleep against it.

Tumbled pebbles, piled where the current would drop them.

Ohko clay stone, pocked with caves that shrimp squabble over.

Porous black stone, riddled with gas holes.

Flat plates layered into a shelf. Shrimp graze the ledges.

Grey rock cut through with white seams. The aquascaper's stone.

A balanced span of weathered rock. Fish love a doorway.

Hollow cactus skeleton, full of holes shrimp hide in.

Pale limb worn smooth. Tannins tint the water gold.

A mossy fallen trunk, hollow at one end. Plecos move straight in.

Thin roots fanning out like fingers. Moss clings to it.

A hollowed trunk. Something usually lives in the hole.

Dense two-tone hardwood. Sinks the day you drop it in.

A twisting driftwood trunk beneath three little moss canopies.

Tipped clay jar. Loaches will claim the inside by morning.

Fluted marble, snapped off halfway. Very sunken empire.

Battlements and an arrow slit. The classic, unashamed.

Three jade roofs with gilded eaves. The little windows never go dark.

A low stone moon bridge, with a clear swim-through arch.

Long ears, heavy brow, staring straight out of the glass.

Tiered garden lantern. The window glows faintly at night.

Red gate half-swallowed by the substrate.

An ancient standing stone whose carved runes still pulse with light.

A marble drum of lit windows under a verdigris dome, telescope still aimed at the surface.

A ring of carved stone around a slowly turning vortex. Nobody knows where it leads.

Green glass half sunk in the gravel, a ribboned letter still inside.

Flukes down, shank leaning. Orange with rust.

Half buried, spokes still turning in the current.

A bronze gun gone green on its broken carriage, shot still stacked beside it.

Lid propped open. Whatever was inside is long gone.

Brass rivets and a round glass porthole, waiting for a tiny tenant.

An eight-point compass rose set into a weathered brass medallion.

Coins heaped round a jewelled crown and a buried sword. Catches every ray that reaches it.

A gilded prow rising from the gravel, its lantern still burning under the bowsprit.

An ancient dragon skull coiled around its gold. The eye still smoulders.

Fluted shell gaping open, pearl-lined inside.

A pearly spiral with warm chamber stripes and a dark open mouth.

A glazed mint shelter with a wide doorway and a brass finial.

A little cone that coughs a stream of bubbles.

A split geode bristling with amethyst and aquamarine. The cores glow on their own.

Towers of living crystal around a glowing gate. The light inside never sleeps.

A giant scallop thrown open around a pearl that glows like the full moon.
