Place and pattern
Where it lives—and how it behaves
Habitat and range
This species is associated with river habitat across South America. Flow, seasonal floods, connected side channels, and access to spawning reaches all shape its river habitat.
Behavior
Uses river habitat for feeding, shelter, migration, or reproduction.
Food-web connections
What it eats and why it matters
Diet
A species-dependent mix of algae, invertebrates, plants, and smaller fish.
Ecological role
It participates in a connected river food web where nutrients and animals move both upstream and downstream..
Remember
One fact worth keeping
Discus dapat tumbuh hingga sekitar 23 cm dan sering ditemukan di sekitar Sungai.
Think like a conservationist
A conservation lens
River fish depend on connected water. Dams, blocked migrations, pollution, and altered flow can matter even when the channel still looks wet.
This habitat lens is not a current population-status assessment. Status can differ among regions and change as new assessments are published; follow the reference links and local fisheries or wildlife agencies for current decisions.
