Riparium: a riverbank tank with plants above the water

A riparium is a partly filled aquarium that recreates a river bank or lake shore: marginal and bog plants grow with their roots in the water and their leaves in the air, usually in planters fixed to the glass above a simple underwater scape. It has little or no true land, needs no CO₂ and runs as a low-tech tank.

What is a riparium?

A riparium is an aquarium run below full so that shoreline plants can grow up out of the water, with roots trailing below the surface and leaves rising into the air. The name comes from the riparian zone, the planted strip along rivers and streams. The scene is all about the waterline.

The style and the name were popularised in the mid-2000s by the American hobbyist Devin Biggs, known on forums as 'hydrophyte'. He founded Riparium Supply to sell hanging planters that clip to the glass and floating trellis rafts, and has written about riparium plants for AMAZONAS magazine. In MOKIZEN's analysis of 591 published layouts, 11 are ripariums; the median one uses about 5 plant species and leaves about 35 % of the frame open.

What is the difference between a riparium and a paludarium?

A riparium has little or no real land, while a paludarium has a true land section. In a riparium the 'shore' is carried by planters, wood or rock breaking the surface, or a sloped substrate. Sources draw the line differently: Wikipedia calls a paludarium with very little land a riparium, Terrarium Tribe says the distinction is disputed, and Biggs defines the style by plants growing above and below the surface along a shoreline. In practice, if you want frogs or other land animals, build a paludarium; ripariums are not made for them.

Which plants grow in a riparium?

Use genuine marginal or bog plants, or houseplants from wet habitats that accept permanently wet roots. Dry-land plants such as succulents rot. Many ordinary houseplants qualify, which is why Biggs has written about using easy-to-find foliage plants.

• Under a closed glass top, Cryptocoryne can flower above the water.

How do you set up a riparium step by step?

Set up the underwater part as a simple aquarium first, then hang the planters and fill to the planter rims. Staggering planters at different heights along the back and sides makes the shoreline look natural instead of a neat row.

1. Choose the tank and decide how high to fill it, leaving open air above the water for foliage.
2. Lay normal aquarium gravel, sand or river pebbles and place the underwater hardscape.
3. Fix hanging or suction planters, or trellis rafts, at varied heights on the back and side glass.
4. Put clay pebbles in the planter base, set the plant in and pack an inert medium around the roots.
5. Fill the tank until the water just reaches the planters and covers the roots.
6. Tie epiphytes onto wood that breaks the surface and plant the underwater zone.
7. Choose the lid: open for tough marginals, partly or fully glazed for humidity lovers.
8. Cycle the water, then add fish and invertebrates.

What do you put in riparium planters?

Use an open, inert medium; never potting soil or compost, which leaches nutrients into the water and feeds algae. Biggs favours expanded clay (hydroton, LECA) because water exchanges freely through it, and it is the most used option. Gensou also lists pumice, perlite, coarse gravel and sphagnum. Terrarium Tribe mentions aquarium soil, but only for ripariums with sculpted banks rather than planters. For planters, start with clay pebbles.

Keep the water level with the planter rim so the roots stay submerged but the stem base stays dry. A drowned crown can rot.

What light, filter and lid does a riparium need?

One light has to cover both the emersed canopy and the water, and ordinary aquarium LED lighting is usually enough; add a clip-on grow light where dense leaves shade the rear. The water section uses standard filtration such as a canister, plus a heater for tropical fish. Keep roots away from filter intakes.

No riparium source gives its own water parameters or photoperiod: the water simply follows normal aquarium values for the fish you keep. The underwater part is best treated as a low-tech scape, and the emersed plants act as strong nutrient sponges.

The lid controls humidity. A closed glass top makes a very humid 'hothouse' for delicate plants but fogs the glass; an open top suits tough marginals.

How do you maintain a riparium?

Care is a normal aquarium routine plus pruning the plants above the water. Tank height matters here: a tank around 30 cm deep leaves little working room, so taller tanks give the foliage more space and make trimming easier.

What are common riparium mistakes?

Most failures come from the planters: the wrong medium, the wrong water level or the wrong plant.

• Potting soil in planters: it leaches and fuels algae. Use LECA, pumice or coarse gravel.
• Water too high in the planter: the stem base rots. Keep it level with the rim.
• Dry-habitat plants: succulents and other land plants rot with wet roots. Choose bog or stream-side species.
• Planting too densely: the front canopy shades the back and the water. Space plants, prune, add light.
• Ignoring pests: emersed leaves get houseplant pests. Inspect often and treat early.
