Appearance and identification

The long-based dorsal fin has many rays; pale lines separate dark markings behind a humped head.

Floor and movement space

Plan the adult footprint early; juvenile housing is not an adult standard.

Aquarium environment

Large fish can dislodge plants and decor. It is not a maintenance-free planted-tank cleaner.

Diet and feeding

Algae alone cannot feed a large adult; supplement with plant matter and suitable complete sinking foods.

Same-species behaviour

Allow ample floor and turning space, strong filtration and oxygenation.
