This is about aquaculture plant and symbiotic organisms in hydroculture systems: the focus is horticultural. Aquaponic and aquascaping organisms are covered in this section.

Hydrophytes[edit | edit source]

Hydrophytes are aquatic plants. Aquatic plants can transport oxygen throughout its stem, unlike land plants. Hydrophytes need plenty of light, as in their natural environments.

Semi-aquatic plants[edit | edit source]

Semi-aquatic plants are adapted to live with its root system in both submerged and land based environments. Only during this time, when a plant's root system is submerged it is involved in hydroculture. (cranberry and watercress)

Symbiotic animals[edit | edit source]

Animals in aquaponics or aquaculture form a symbiotic relationship with plant-life. Aquatic animals need some light like in their natural environments.

Freshwater[edit | edit source]

Goldfish, Loricariidae catfish, snails and shrimp eat algae.

Plant-like animals[edit | edit source]

Coral are a saltwater animal that require high maintenance. There are freshwater and saltwater sponge.

Aquaponics[edit | edit source]

Aquascaping[edit | edit source]

Saltwater aquascaping is for aesthetic reasons. Coral, sponges and saltwater plants may (possibly) form a symbiotic relationship.

(Aquarium keeping, fishkeeping, other symbiotic animals and aquascaping)

Aquatic gardening[edit | edit source]
