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 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]

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]

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


Goldfish, Loricariidae catfish, snails and shrimp eat algae.

Plant-like animals[edit]

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



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

Aquatic gardening[edit]
