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.

A milky quartz chunk, all broken facets and glassy edges.

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.

Cut canes of different heights, lashed together at the foot.

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.

Terracotta pots, one tipped on its side. Every loach wants that one.

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

Red and white stripes leaning in the silt. The lamp still turns.

A lion-bodied guardian with a chipped nose, lying patient in the sand.

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 coral-crusted golden throne, trident planted beside it. Still waiting for its king.

A glass-domed city of white spires, every window lit. The legends were right.

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.

A grinning skull on crossed bones. Tetras swim straight through the eyes.

An iron-hooped cask on its side, bung long gone. Somebody lives in it.

Flukes down, shank leaning. Orange with rust.

A bronze bell on a broken yoke, its ship's name still engraved.

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.

A little research sub nosed into the gravel, portholes still lit.

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

One giant tentacle curling out of the gravel, wrapped round a snapped mast.

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.

Brass rings and enamel planets ticking round a little glowing sun.

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.

A nest of smouldering golden twigs cradling an egg of living flame.
